2 Motivation Existing methods of defining 3D models within HFSS have been sufficient since the introduction of the product many years ago. To better align with customers existing product design flows, ANSYS has long had a policy of being CAD agnostic. To that end, the bidirectional CAD associativity, already available for Mechanical and Fluids designers in the ANSYS Workbench, is now accessible to Electromagnetics users as well. 2

3 Agenda Existing 3D model design flow Example of MCAD Integration without parameterization Example of MCAD Integration with parameterization Example of MCAD Integration with parameterization AND Coupled Physics 3

4 Existing 3D MCAD Integration Flow Flow is a misnomer Collaboration amongst design teams is often fractured at best 4

7 Heritage ANSYS has a long history of being MCAD-agnostic for Mechanical and Fluid simulation Now, this capability can be applied to all the 3D Electromagnetic products as well 7

9 Examples of MCAD Integration Demonstrate two methodologies for using MCAD integration with HFSS 1. Integration without parameterization Replaces file-based model transfer Uses the following licenses HFSS (hfss_desktop, hfss_gui, hfss_solve) MCAD license ANSYS Geometry Interface license (piproe, etc.) 2. Integration with parameterization Allows greater model reuse and design exploration Uses the following licenses HFSS (hfss_desktop, hfss_gui, hfss_solve) Optimetrics (hfss_optimetrics) MCAD license ANSYS Geometry Interface license (piproe, etc.) 9

10 MCAD Integration without Parameterization 10

11 MCAD Integration w/o parameterization Insert Geometry cell in Workbench schematic Right-click on Geometry Cell and select Import Geometry to Browse for file 11

12 MCAD Integration w/o parameterization Insert HFSS component into Schematic Click on the Geometry cell, drag it over the Geometry cell for the HFSS component and release 12

13 MCAD Integration w/o parameterization Refresh Project brings in Geometry from MCAD tool GbX model courtesy of Assign materials, excitations, boundaries, setup, and run simulation 13

15 MCAD Integration with Parameterization 15

16 MCAD Integration with parameterization 16

17 MCAD Integration with parameterization Insert Geometry component into schematic, right-click, and select Import Geometry, and browse to the SCDM file Click on the Geometry cell, and drag it over the Geometry cell in the HFSS component 17

18 MCAD Integration with parameterization In Workbench, click on Refresh Project to transfer geometry from MCAD system into HFSS 18

19 MCAD Integration with parameterization You may need to enable the Parameters to be passed from WB into HFSS To do this, select the Geometry cell in the schematic, and view the properties The Parameters property needs to be enabled (checked) The Parameter Key value is a text filter to apply to the linked geometry Sometimes with MCAD models, there can be many variables One way to limit the number of variables transferred to WB, is to add a prefix to the variables in the host system 19

20 MCAD Integration with parameterization Selecting the Geometry component from the model tree will enable access to parameters from the Workbench cell including the Parameters tab In order to perform any type of parameterization within Workbench, we need to create a WB-specific variable In the Value field for the offset, we will enter WBoffset, and define this as 0mm From here, we set up the problem as normal, assigning materials, boundaries, and excitations, as well as adding the Solution Setup 20

21 MCAD Integration with parameterization In the WB Schematic, we still don t have any parameters identified This would be identified by a P block linked to the HFSS project showing variables as an input, and calculations as the output We create an output variable to calculate the power split between the two output ports 21

22 MCAD Integration with parameterization We then edit the properties of the DefaultDesignXplorerSetup in the HFSS project Include the use of the WBoffset variable by enabling it on the General tab We add a output calculation to the Calculations tab 22

23 MCAD Integration with parameterization We now have a parametric Workbench schematic that can be used with DesignXplorer 23

24 MCAD Integration with parameterization Clicking on the Parameters bar to edit the parameters and look at the outputs allows you to see the Design Points (DP) which have been solved You can change the value of the Parameter, P1, Update Project, and HFSS will be run to produce a new output Parameter, P2 Running HFSS in this manner will require the MCAD license to be pulled as well as the HFSS solver license 24

25 MCAD Integration with parameterization The real power of parameterization is the ability to run Design of Experiments with Goal-based Optimizations and Six-Sigma Analyses 25
