FEM Elasticity Model March 4, 2018, 7:16 p.m.
Hi all,
Is there a place in the docs that describes how the FEM Shape Stiffness and Volume Stiffness relate to elastic moduli like Bulk/Shear moduli or Poisson's ratio. It seems that Volume stiffness is close to bulk modulus and shape stiffness to Shear modulus (or Young's modulus?). Is that so?
Also, does Houdini use a corotational elasticity model or neohookean (or something else)?
This is useful to know for reproducing simulations from other FEM simulators.
Thank you!

Hi all,
I was toying the cmake system for building HDK sops and it seems that the search path for houdini shared libs isn't right. I get the following messages after calling make:
It seems like $HFS is being prepended to the search path for some reason. I resolved this locally by changing HoudiniConfig.cmake.
