Field Output unit in Abaqus

[ShiningEngineer]

Hello all,

I have a question about the unit system of simulation results in Abaqus. I have built a simulation model and modeled my model sketch directly in Abaqus in millimeters. My input data for the hyperelastic material model are MPa and strain (specified as 0.6 instead of 60%). Furthermore, I have specified a forced deformation in millimeters. Now I query the displacement at a targeted node via the Field Output, this should be output in millimeters by Abaqus, right? Additionally I have a Field Output that tracks the reaction forces on the surface of my model where the forced deformation was applied. Are the reaction forces I summed up on the surface of the simulation results now in Newton? Or already in Newtons/mm? If they are in newtons, is it legitimate to simply divide the reaction forces by the contact area manually in post-processing? Is there also a way for Abaqus to directly output the reaction force per area, i.e. N/mm² = MPa?

Thanks a lot

If you search for "Abaqus units", you will find helpful tables wirh consistent units for different unit systems. In the case of SI(mm) system, displacements are in mm while forces (including reaction forces) are in N.
