5 The Animator4 Viewer is based on the kernel and the graphical user interface of Animator4. It can be used to import simulation datasets prepared with Animator4 and allows a limited interaction with the imported datasets. Animator4 Viewer can change datasets, create new sets or delete them. This guide is mainly based on an exemplary dataset (Can.a4db) which can be be downloaded from Contents: CONTENTS 1

7 CHAPTER ONE IMPORT DATA Animator4 Viewer can be used to import databases generated by Animator4. The main focus is to use datasets stored in the database4 format ( *.a4db ). Nevertheless Animator4 Viewer can also read the a3 database files for compatibility reasons. Please note that you can only import one database at a time and that the import is limited to the full dataset, i.e. it is not possible to import subsets of a database. Upon every startup, Animator4 Viewer will open a file dialog which can be used to locate the database file. You can access the open dialog at any time from the menu bar. Select the database4 file (Can.a4db) in your download directory and click the button Choose button. 3

9 CHAPTER TWO HANDLE VIEWS Animator4 Viewer can handle multiple views to compare models from different perspectives and different states or to observe multiple curves simultaneously. Animator4 Viewer supports all of the five different Animator4 view types: Model, curve, video, image, flc and presentation. For each type an unlimited number of views can be created. To add a second model view select the menu entry Windows Add View Model View from the menu bar. To switch between the views open the menu entry Windows in the menu bar. All existing views will be listed in this menu. Select one of the views from the list to get this view into the foreground. You can also arrange all views in the workspace of Animator4 Viewer. Open the menu Windows Arrange Views from the menu bar. Select one of the entries, for example Horizontal Tile, to arrange the views. 5

13 CHAPTER THREE CONTROL MODEL DATA 3.1 Camera Control You can control the geometry data in the model view by using either different input devices like the mouse or a spaceball or by using the View dialog (Model View) to translate, rotate or scale the view. All translations and rotations in Animator4 Viewer are defined in screen coordinates with the x-axis in horizontal direction, the y-axis in vertical direction and the z-axis in the direction perpendicular to the screen surface. The dynamic rotation center is located on the node nearest to the mouse pointer. If the mouse pointer is outside of the model, the rotation center is set to the middle of the model view. The global coordinate system can be used to check the position of the model. It is located in the lower left corner of the model view Using Mouse Control To control the camera position with the mouse, hold down the left Ctrl-key, move the mouse and press the left mouse button middle mouse button right mouse button left + middle button or use the mouse wheel to rotate about the rotation center to move along x/y axis to rotate about z axis to zoom in and out Ctrl + Ctrl + Ctrl + Figure 3.1: Graphical illustration of the camera movement Note: The view can always be centered and fit to the window using Ctrl-F9. 9

14 You may use the Shift-key instead of the Ctrl-key to change the view in the wireframe-like edge mode, where only the edges of your model are drawn during the change of view. This mode reduces the rendering work significantly so the handling of very large models will be much more user-friendly Using the View dialog The View dialog can be used for changing the parameters of the camera to specific values. To open the View dialog select Model View from the menu bar. The upper part of the dialog shows the current view parameters. The values will be dynamically updated if you change the view by using either shortcuts or keyboard and mouse. The parameters in the View dialog can be changed by hand as well but won t be executed until the Apply button will be clicked. To adjust the view properly it is necessary to understand some backgrounds of categories given in the View dialog. A detailed description is either given in the Animator4 Reference Manual or User Guide. 3.2 Handle Model Data Slot Selector Animator4 Viewer can handle multiple datasets in a single session to efficiently compare variants or to show different attributes of one model at the same time. Multiple datasets are orga- 10 Chapter 3. Control Model Data

15 nized into slots in Animator4 Viewer, each slot can independently hold geometry data as well as displacements and other results. You can control the visibility of slots using the slot manager in the command area. To colorize all items of one slot in the same color, click the color button in column C. This helps to associate items with a slot when working with multiple slots. To toggle between uniform and standard colors, activate or deactive the color button in column C. You can easily toggle the visibility state of single slots using the slot selector. To toggle the visibility of a model, activate or deactivate the switch in column V Interaction Modes The methods of selection given above can be used to interact with the items in the model view. You have erased some items before. You can further identify, colorize or stylize items. The interaction mode can be set with the Mouse Control toolbar as given in the picture below. Select Item Erase Item - Activated Identify Item Stylize Item The interaction modes available in Animator4 Viewer are explained in the following: Select Selected items are highlighted and can be used for the operations erase and identify. You can access these operations by using the context menu, which changes its menu entries when in selection mode. You can use the Reset Selection entry of this selection mode context menu to reset your selection or simply revert a selection by clicking a selected item again. Identify The selected items are highlighted and marked with their ID-number. The identification markers can be deleted by using the toolbar menu Identify Reset or by clicking on the selected items again Handle Model Data 11

16 Erase Selected items are erased (hidden) from the model view. Erased items can only be readded together. To re-add them, right-click into the model view and select Add All or use the Common utils toolbar button Add All button. Stylize Selected items are stylized using the style selected in the Mouse Control toolbar Item Filters and Actions One task when working with Animator4 Viewer is to select items and to apply actions on them. This chapter will introduce the basic graphical selection methods available. In order to test the selection modes you have to activate one of the action modes in the Results toolbar. Item Filters: Graphical selection is based on three selection modes: Point&Click: You can select single items in single selection mode. Simply click on the item you want to select with your left mouse button. Rectangular Window: You can select multiple items located in a rectangular area by using the rectangular selection mode. Initiate the window selection mode by pressing the left mouse button at the position on screen where you want the rectangular area to start. Hold this button and drag the mouse to draw the rectangular area. All items within this rectangular area will be selected. Polygon Window: To have a more precise control over the items to be selected you can use polygon window selection. To activate this selection mode, first click the left mouse button. Hold the left mouse button and additionally click the right mouse button to set the first point of the polygon. Release all mouse buttons and set additional points by clicking the left mouse button. If you want to remove the last segment of the polygon, press the middle mouse button. If you have finished drawing the polygon press the right mouse button to confirm selecting the items within the polygon area. Reset Selection: To reset your selection you can either press the Esc-Key or use the Reset Selection of the context menu in the model view. Item Actions: In model view you can select nodes, elements, parts, labels or images. You can define the kind of items to be selected by using the Mouse Control toolbar or the context menu. 12 Chapter 3. Control Model Data

The tabs selects the type of data to display. In tab Parts all parts are listed with their ID, name and element type. In extended mode also the material ID, the thickness (for shell parts) and if available the groups and layers in which the parts are referenced will be shown. In tab Materials all materials with ID, name and element types are shown. In tab Groups, groups tree is displayed with all the child elements, parts and nodes. In tab Layer layer tree is displayed with corresponding child layers and part names. Switch to the tab Groups. The tree shows the hierarchy of the selected slot s model down to the level of parts. Layers and parts are listed by their names in the tree. With the Parts dialog the visibility, rendering style and color of the items can be set. The render style buttons select the display mode for the selected items. When a button is pressed the style is directly applied to the currently selected items. Right-click on the group Can in the dialog list and select the menu entry Show This. All items except the items of the group are erased from the model view. Select the group Can in the dialog list and click on a render style button to change the style of the can. 14 Chapter 3. Control Model Data

19 CHAPTER FOUR DISPLACEMENT DATA 4.1 Animation Control An easy way to control animations in Animator4 Viewer is given by the animation bar in the slot selector. The main buttons and functions of the animation bar are given in the following: Use this slider or use the input field to set animation speed in frames per second (fps) Set animation speed to maximum. This is the default setting as very large models will limit the fps anyways. Forward loop Backward loop Forward once Backward once Forward/Backward Speed Start animation in mode given below Loop continuously through states in time Loop continuously through states in reversed time Single loop through states in time Single loop in reversed mode Loop continuously with forward run following a backward run Open speed control widget Stop animation active if animation is running Step forward to next state. Step backward to previous state. First state Last state Set state by mouse Set point of start and end of the animation 15

20 4.2 Switch between displacement datasets Animator4 Viewer can handle multiple state sets holding different displacement result sets. The state sets and all corresponding states are given in the States dialog. This dialog can be used to switch state sets and single states. Open the States dialog by selecting Model Switch to the view 1: Model with the View selector. States from the menu bar. Select one of the states in the list. At every selection, the display will immediately change to the selected state. If several displacements datasets are included in a slot, you can switch between these datasets by clicking on the dataset in the States dialog. Select the second state set Eigenmode 5, Freq in the States dialog. This state set visualizes a eigenmode of the can by a harmonic oscillation. 16 Chapter 4. Displacement Data

21 CHAPTER FIVE FUNCTION DATA 5.1 Display function dataset Animator4 Viewer can be used to display function data. You can observe function data on the entire model. Depending on the type of input data Animator4 Viewer can display function data projected onto the model as color range or in vector or tensor representation. You can use the Results toolbar to access all of the fringe plot related settings such as choosing the function to plot, setting the slot and state set or switching between nodal and element fringe plot display. Fringe Plot Selector IsoLine Toggle Switch Layer Selector Slot Selector Function Selector StateSet Selector Dynamic AutoRange Switch AutoRange Button Display the function stored in the dataset as an element fringe plot by using the Fringe Plot Selector from the Results toolbar. Note: Displaying function data in state 0 isn t possible. Make sure to set another state by using the animation toolbar. 5.2 Switch between function datasets To switch between the function datasets you can use the Results toolbar. Open the Function Selector selector in the Results toolbar and select the second function data Node velocity. 17

22 Function Selector Animator4 Viewer will change the graphical surface of the model to the second function dataset. If you are switching between the function datasets, it could happen that the range of the function bar is not set to the maximum and minimum of the functions s data values. With the button Autorange button you can automatically set the lower and upper bounds of the function bar according to the currently selected function s values. Click on the button Autorange button in the Results toolbar to automatically set the function bar range. Autorange 18 Chapter 5. Function Data
