FEM DOPEmbedded geo issue

Morning,

Woking on some FEM stuff but having some issues. First image you can see the nodes used to create the scene.597a93bbc2d5a_FEM1.thumb.jpg.b7bcfc86e0107d6adc111cb8e2cd2b85.jpg

The transform has CHOPS applied to the rx value with some noise for animation. Point deform captures this animation. The isooffset is used to group internal points on the tets and used for constraints in the sim.

In DOPS its set as an organic mesh and the target is set to follow the animation.

Everything works great (love FEM) but.... having some bad results on the embedded geo as you can see in the first image (FEM 1 ) Why do the results come out like this? It also doesnt follow the sim very well.

If i use just a standard point deform the reults are better and it follows the animation tighter.

So why do we use the Embedded Geo option? How can the result be improved.

Weird job where the client wants unicorns abused this way... but will upload a .hip with simpler geo when I have chance.

Cheers

looking at the resolution of the tet mesh in the middle image i would say its perhaps a little high so the embedded geo is struggling a bit to pick which point to work with.  Maybe try lowering the resolution of the tet mesh (solid embed) perhaps and see if that smooths out the deformation on the embedded?
