Hello Friends,

I wanted to know how to access the value of a variable for all integration point inside UMAT.

We can get access variables in integration points from .odb file in UMAT. We can also write a .dat or .txt file inside UMAT which gives us all the values from integration points. but it is a very slow process.

I wanted to for example have the access to Zigma11 for all integration points inside UMAT so I can save them as state variables. For example, C3D8 has 8 integration points, so I want to get 8 values for zigma11 in umat to save them as state variables 1 to 8 which gets updated at each increment.
