Hey.
I am running a simulation and I get multiple "Slave surface is a node-based surface used with surface to surface approach. In order to obtain improved stress accuracy with this approach, an element-based surface should be used instead."
When I created the constraint I selected surface both times, instead of node region, so I don't understand why I am getting this warning.
If anyone could tell me what I'm doing wrong or how to change the surface from node-based to element-based I would be very grateful.
Thank you

You didn't mention the name of the software but I assume that it's Abaqus.

Can you share a picture showing the surfaces that you selected ? Did you check their definitions in the input file ?

Yeah, it's Abaqus. Checking the INP I found some surfaces with node type.

Thanks for the help
