How can I convert section of 3D mesh to 2D mesh?
Hello everyone, I have a difficulty to convert section of 3D mesh into 2D mesh. Let me explain my situation. I have a 3D tetrahedral-meshed model and I'm performing analysis on specific section. But since I have many DOE, I often need to modify the mesh. I think It is more easier to performing analysis using a 2D…

Problem with Cohesive Zone Modelling (CZM)
Hi everyone, I'm using Optistruct to perform a Double Cantilever Beam adhesive debonding simulation and I'm getting illogical results. As you can see in the picture the adhesive is being stretched a lot and the bigger damage can be seen more towards the fixed end of the beam, which is not how it should be. Could anybody…

HyperMesh 2025 수동 메싱 시 점진적 요소 크기 조절 관련 문의
HyperMesh 2025를 사용하여 구조물 형상에 대한 Tetra 메시를 생성하는 과정 중 문의사항이 있어 메일 드립니다. 아래 이미지와 같이 전체 형상은 Adaptive Wrap Mesh 기능을 활용하여 메싱한 결과이며, 곡면에서는 세밀한 요소를 적용하고, 직선면으로 갈수록 점진적으로 요소 크기를 키우는 방식으로 메싱하고자 하였습니다. 하지만 아래와 같 수동으로 영역을 나눈 뒤 Surface Mesh 기능을 사용하여 메싱을 시도하면, 아무리 변수들을 조정해도 아래와 같이 요소 크기가 급격하게 변화하거나 거의 차이가 없는 형태로만 생성되어 의도한 점진적인 메쉬 밀도 차이를…

Joining of mirrored components.
I have two 2d meshed components which I mirrored at their symmetry plane, but I can't find a way to join the (congruent) nodes. Using stitch or surface repair screws up the mesh, as its remeshing the components. Mirrored surfaces seem to be violated some how. Is there a way to simply connect two meshes? I'm working with…
