Developing User Material Subroutines in CALCULIX: 4 UMAT neural network example
In this post, we explore how to integrate a neural network in a user material subroutine (UMAT) for CalculiX. The main idea is that the material’s plastic behavior is learned by a neural network and embedded into the UMAT code, in combination with a classic linear elastic model. We’ll use a UMAT example with the […]
