Material model exported by Multiscale designer for Abaqus not working

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.

    Hi Atrash
    In the installation path of Multiscale Designer we have included an abaqus example file!
    "hwsolvers\demos\MultiscaleDesigner\examples\abaqus\IM\solid"
    If you look into that you will see how the user mat in abaqus need to be defined!
