EralpDemir commented 1 week ago

Hi, UMAT is more comprehensive than VUMAT indeed. It should be easily transferrable to VUMAT.

For efficiency the jacobian calculation can be removed in the calculations. In the long-run I will prepare a VUMAT for explicit calculations.

But ignoring that, it can easily transformed to VUMAT with careful assignment of inputs and outputs in the subroutine.

Hello Eralp Demir,

Could you please provide a detailed tutorial on how to convert UMAT to VUMAT? I would greatly appreciate it.

Thank you!
