Neo-Hookean model in XPBD?

Post by GeorgeJennings » Thu Apr 20, 2017 11:47 pm

Hi,

can the classical nonlinear elastic material models (like the Neo-Hookean) be used in the XPBD framework?
In the paper they only use the simple St. Venant Kirchhoff elastic model.
Is the simulation going to remain stable while simulating using more complicated models under high time-steps (e.g. 1/20 s)?

(I consider a 3D tetrahedral model as a simulation object.)

Thanks.
