Hi , Guys .
Recently , I meet problem about mesh of object which hollow beam. So, when I solve "the Mesh" for beam , and get 3 errors (look at the picture below )
So,the errors are : 1) One or more entities failed to mesh. The mesh of the bodies containing these entities may not be up-to-date. Â However, meshing might be successful on the other entities.
                              2) The surface mesh is intersecting or close to intersecting, making it difficult to create a volume mesh. Please adjust the mesh size or adjust the geometry to fix the problem.                               3) A mesh could not be generated using the current meshing options and settings.
. Can you help me please and how to fix with good procedures .

Hi
It looks like a thin part - perhaps use surfaces/shell and then use shell elements to mesh (now with 3D mesh your aspect ratios are not good since it is thin).
All the best

Thanks for your response and I appreciated. Yes, maybe it's thin part from the size of hollow beam, (Length= 150000mm , width = 15000mm , Height= 15000mm, and thickness overall = 10 mm ). -Â However , I still can't get it what you mean to fix it. what you mean by saying " use surfaces/shell and then use shell elements to mesh" and where to fix it , (at ansys spaceclaim or at ansys design modeler or at ansys discovery ) . Please tell me more detail about the solution . Thank you

Ahh , I just want to say, thank you so much for your clue . It's thin structure, right ? I have fixed the problem . Thank you Erik . You bring me to succes to solve the problem and save my life .Â

Hi
I would suggest to take our course in spaceclaim:
https://innovationspace.ansys.com/courses/courses/solid-modeling-with-ansys-spaceclaim/After that, we have another good course to describe meshing etc. in mechanical:
https://innovationspace.ansys.com/product/get-started-with-ansys-mechanical/Finally aslo see the edx ansys course for some theory (say shell elements what they are and theory - solid 3D elements., etc.)
https://www.edx.org/learn/engineering/cornell-university-a-hands-on-introduction-to-engineering-simulations
All the best
Erik

Actually, I have been doing that , and I understand the steps. Once Again , Thanks . I appreciated your response .Â
