Axisymmetric analytical rigid: multiple surfaces? 1

[yw5aj]

I have a simple model - an axisymmetric analytical rigid body, with the shape of a rectangular.

I'd like to assign different friction coefficients to different edges on the rectangular. However, when I select surfaces, all the edges are always connected to be one surface. Is there a way to break it into multiple surfaces, constituted of different edges?

Thank you!

OK - got one answer from SIMULIA Learning Community, credits to Matthias Ernst:

"No. In the input file one analytical rigid is one surface keyword. And that surface is used in contact.

Maybe you get it done by creating two analytical rigids that are placed right beside each other. You can connect the ref nodes (with equation or coupling or beam connector) to make them behave as one."

Thank you Matthias!

A meshed deformable part, that is declared as rigid in Interaction-module (Constraint->Create->Rigid Body) would be another workaround.

@Mustaine3 That's a great way to do it too. Thank you!
