[SOLVED] How the object deforms in this specific example?

[Zahra]

Hi,

Until now, I have always added external force to the object to deform it, but now I noticed the “TutorialForceFieldLiverTriangleFEM.scn” in which the liver deforms, however I can not find any external force applied to it. Would you please guide me how the liver in this example deforms?

Best,

Hey Zahra,

The scene TutorialForceFieldLiverTriangleFEM.scn highlights a FEM implemented on triangles, i.e. surface elements. The external force you notice is the gravity itself. If you open the XML scene, you will note :

<Node name="root" gravity="0 -9.81 0" dt="0.02">

showing that the gravity is set in the y-direction. With FixedConstraint, the liver is therefore under gravity. Defining external forces to deform the object is the correct formulation.

Best,

Hugo
