Material model exported by Multiscale designer for Abaqus not working

Atrash

Hi,

I've created and defined the unit cell of my honeycomb in Multiscale Designer; and I wanted to export it into Abaqus solver. However, I kept getting the following error despite having imported the .inp file generated by Multiscale Designer and having the mdsMAT.dat file in the same directory. Any ideas? Thank you.
