Solving errors when creating a deformable surface in MotionView

Hi Everyone,

 

I'm trying to create a deformable surface for one of my projects and am having difficulty generating it. When I go to generate the surface I am met with the following error message.

I assume this means my .fem file is of poor quality/uses the wrong elements but I am not sure whether this is the case or whether it is even what I need to do to my mesh in order to fix the issue.

 

Any help explaining the process for properly creating the .fem files for deformable surfaces or explaining what I can do to solve this error would be greatly appreciated. The surface I am trying to make deformable is shown below (the points represent the interface nodes).

    Hi @Shaun Smith,

     

    To create a deformable surface, you should go to the general toolbar and click Macros > Create Deformable Surface from FEM.

    Insure your .fem contains ONLY CQUAD4 elements (shell elements with 4 nodes only). By doing this, you should avoid producing undesirable errors.

    BR,
