I am working on the Motorcycle model so making the bike model in motion view for forces. So, in initial stage we have to import fem file or cad file will do the work ?Capture.PNG.4dc1d81669d2b6838c18adaa87c8fb91.PNG

    Hi Sudhanshu,

    If you are only analyzing forces on the body, either fem or cad file will do the work. They are only used in the graphic entities for visualization purpose.

    Hello Sudhanshu - Importing an FEM or CAD only represents the body as a rigid body with the mesh in FEM or the geometry in CAD aiding as graphics for visualization only.

    For the initial study, it is generally sufficient. However, you may want to represent the flexibility of the frame by representing it as a flexible body. This is done by converting an FE model to a flex H3d. The Flexprep utility under FlexTools menu helps in doing that. Apart from  a well formed FEM, you need to know the node numbers where the body will interface with other bodies through some joint, bushing or forces.

     

    Hope this helps

    Praful and Felipe thank you for your replies.

    There's one more doubt, during the modelling I have used Bistop function to create GAP function but it is not calculating it.  What could be the possible reasons for this error.1.PNG.295191d374b9b3c0b6312f2b40a2dab0.PNG
