warp Material optimization

Hello! I'm trying to use Warp to do some material optimization experiments. Is there a way to make sure the material is uniform? Also, is there an example for optimizing the k_mu and k_lambda parameters of a tetmesh?

I tried computing the gradient of self.model.tet_materials but all its entries are very close to zero. I am also not sure how I can make the material uniform (e.g., make sure k_mu and k_lambda are the same for every tetrahedron) and then optimize the material parameters.

Thanks!! :)

Hi Honglin,

Thank you for the question, this would be a great example for differentiable simulation in Warp. We are preparing a material optimization demo in Warp right now and will have it released very soon!

Thanks, Eric

Hi Eric,

Thank you soooo much for that! Please let me know when it's online. :)

Best, Honglin

@MiguelZamoraM added an example to do this in #419.
