Preprocessing Roll Thru Mode Roll-Thru: move inside the model

cannot move through your model, you just zoom closer and closer

screen direction, everything behind that is clipped Zoom in

9 Preprocessing Roll Thru Mode Roll-Thru: move inside the model With Roll-Thru off (and in all previous versions of Femap) you cannot move through your model, you just zoom closer and closer Roll-Thru moves the viewer s eye to a certain depth in the screen direction, everything behind that is clipped Zoom in enough and you re inside, and can turn around and see what was behind you Page 9

54 Solver Support ANSYS & Abaqus CBUSH/PBUSH Input General Issue: ANSYS and Abaqus do not have an element which exactly matches the (CBUSH/PBUSH in Nastran) Spring/Damper element in Femap Additional Requirement: Spring/Damper elements must behave like CBUSH/PBUSH when solved with ANSYS or Abaqus, otherwise different results are calculated Possible Solution: Simply include stiffness and damping of Spring/Damper elements when creating input files for ANSYS or Abaqus Our Solution: Spring/Damper elements are written as MATRIX27 elements for ANSYS; written as *MATRIX INPUT for Abaqus; with matrix values (stiffness and/or damping) calculated using the same approach as CBUSH/PBUSH Limitation: nonlinearity and frequency dependency are ignored, as the matrix entries are calculated only once Page 59

60 Solver Support CBUSH Translation Notes For ANSYS: PBUSH to MATRIX27. K and B to two elements, one for K, another for B. SPRING/DAMPER to COMBI14. To Ground : creating a dummy node and apply D,dummyNode,ALL,ALL. For Abaqus: PBUSH to *MATRIX INPUT, *MATRIX ASSEMBLE. K and B, two matrices. Spring (K input) to SPRING2/A, Damper (B input) to DASHPOT2/A. PBUSH to Ground, only top-left quarter (11) sub-matrix is written. SPRING to Ground (K input) to SPRING1. Damper to Ground (B input) to DASHPOT1. *MATRIX INPUT, *MATRIX ASSEMBLE not applicable to analysis other than statics/mode, for other analysis, CBUSH is not translated and warning is issued. Page 72

matrix (K,B,M) is added to Femap to handle its input from Femap

61 Solver Support MATRIX27 input from Femap Because PBUSH is translated to MATRIX27 of ANSYS and MATRIX27 is 12x12, A 12x12 matrix (K,B,M) is added to Femap to handle its input from Femap Still keep 6x6 matrix input. A switch to12x12. Choice of K,B,M. Accessed here Page 73
