- 23:45, 12 July 2025 Python material (hist | edit) [20,556 bytes] S g (talk | contribs) (Created page with "It is possible to use Python to compute stress and modulus for FEAP. This can be helpful during early stages of material model development. Here is a very simple example for a linear elastic material model. The idea is to create a user constitutive model (umatiXX.f and umatlXX.f). To use the material, one first opens up a SOCKET in Python (this is the server). Then FEAP, once started creates a client that sends strain and material parameters over the socket. Python...")

In a FEAP computation the boundary codes on the driven nodes can be dynamically changed by changing the values in the <code>ID(ndf,numnp,1:2)</code> array. In particular if for a given dof and node number the value of <code>ID( , , 2)</code> is set to zero...")
