Interface MPMMaterialContext

What a material's GPU hooks see of one particle (TSL nodes). Matrices are mat3 nodes. Note TSL's matrix–scalar operators: M.mul(s) and M.add(N) are fine, but M.sub(s) and M.div(s) are not (write M.mul(s.reciprocal()), build mpmIdentity() for I).

Properties

C

C: any

APIC affine matrix C ≈ ∇v, the velocity gradient (mat3; for viscosity).

dt

dt: any

Substep, seconds (float).

F

F: any

Elastic deformation gradient F (mat3).

J
