Mesh problem

[mich.ke]

Dear STKO Team
Hello, I am a student of the University of Cagliari and it’s the first time I use your software.
I’m modeling a reinforced concrete beam and I have a problem with the mesh. After using the "Subtract" command to make the solid unique with reinforcement holes, the mesh is not generated. As a consequence the analysis does not start. Could you help me?

Thanks

The geometry resulting from your subtract operation is not correct. Probably due to some imperfections in the geometry you used for subtraction.

Anyways, using the approach of creating holes for rebars and linking linear (beam-elements) rebars to a solid model can be cumbersome and expensive.

Why don't you use the ASDEmbeededNodeElement constraint to embed rebars inside the solid volumes without creating holes?
We have a webinar about this approach

Thank you, I found the webinar and will follow your advice.
