Mesh refinement at singularities

Hi,

I have a question about node mesh refinement. I am currently experimenting with surface structures and singularities. In a script, I found a figure where the mesh refinement at the node was chosen so that the resulting section only shows the stresses at the support edge. (see image)

I have been playing around with the node mesh refinement but cannot achieve the same result. The file is attached:

Could you tell me where the difference lies and how I can achieve similar results in the section? I find it quite an elegant solution.

Best regards and many thanks,

Lennart

Hello Lennart,
you can achieve this internal force distribution with a cutout of the support area by defining the node support as "stiffness via fictitious support":

That's exactly it! Thank you very much, Rebecca :)
