Parallel Multiscale modeling in ABAQUS using UMAT

Hello everyone,

I am currently in the process of implementing a multiscale modeling approach in ABAQUS/Standard.

Here is what I am doing.

Macroscale ABAQUS model <--> UMAT <--> Python script <--> Microscale ABAQUS model

So basically the microscale model is being called at every macroscale integration point. The UMAT passes the required data to python as command line arguments and the python script returns the stress and tangent modulus in a text file.
