inverse calibration using Abaqus and Mcal for a compression test

I have experimental data for the compression tests (large deformation) of a single 3D printed Nylon filament.

I created a FE ABAQUS model with the same boundary conditions, loading as experimental test to perform an inverse calibration using Mcal and abaqus external solver to define the best material behavior.

(attached  .mcal files)

issue: why after more than 10 hours (after click " run once" in mcal) it is still running without any results.

wondering if I define the temporary path and abaqus path in preference correctly (below screen shot) 

you can find the files created in the folder during running:

or something is wrong with the model?

Your help would be highly appreciated.
