Getting The Position Of Two Mapped Volumetric meshes

[MA]

Hello,

My scene is composed of two mapped volumetric meshes and I want to compute the total displacement. There is a force applied to the meshes, although I can compute individually the displacement of each mesh, should be the total mesh is the summation of the two?

Hi @ma1991

Thanks for your question.
Positions of an object are stored in the component MechanicalObject. This component is storing the degrees of freedom / state information: rest_position (equals to initial position if not specified), position, velocity.

I would therefore recommend to access the initial position from MechanicalObject.rest_position and the current position from MechanicalObject.position. Your total displacement would therefore be: position-rest_position.

I hope this helps
Best wishes,

Hugo

Many thanks, Hugo! I think I should more elaborate on my questions, the purple and blue parts have it is own displacement stored since I mapped two different volumetric mesh, and now I have a displacement of each volumetric mesh, should be the net their summation?

Also, the results do sound not realistic, I made sure the units are unified, should I use this part “TetrahedronHyperelasticityFEMForceField”?

Thanks
