Mesh Connect! #3403

Closed MRChung-EC closed 2 weeks ago

MRChung-EC commented 2 weeks ago

Description of the modifications

If the mesh's Connect function is used in ansys mechanical, various bodies are overlapped in various shapes, and nodes are shared in all overlapping phases, so linear analysis is possible as if the bodies are one without adding a separate connection option. It can be more efficient, especially in the shape of an aircraft with a complex structure, but I want to run it in APDL, so I can't find commands that perform the same function. If you know a similar command, please share it. This is because Mesh's Connect can be interpreted as the same structure. Primemesh and Mechanical used it together. KakaoTalk_20240905_164941443

Hi @MRChung-EC There is no one command in Mechanical APDL to recreate this. Remember WB Mechanical and Mechanical APDL do not have a one-to-one correlation with respect to features/functions. WB Mech has more meshing technology that was either developed for it or came from the CFD world. And WB Mech has some of MAPDLs meshing functionality.

Depending on the type of Mesh Connection you are trying to replicate from WB Mech, MAPDL does have geometry editing or creation commands that you could start with. Then some combination of cad boolean(s), mesh sizings, and/or entity merging could be used to recreate the mesh connection in MAPDL.

Closing issue, but feel free to keep the discussion alive here.

And it is possible that merge line to surface? Or keypoint to surface. Because much of line didn't share same plane
