Description: I have installed the above S-Frame student edition software. However, when I try to click New 2D Model I get Runtime Error 381. I then need to use task manager to kill the application. I have tried reinstalling multiple times and various other methods. Product/Topic Name : S-FRAME, S-STEEL & ICD 2026.0…
I have imported a 3D structure from GMSH to FEKO to find its RCS(imported mesh, not geometry). In FEKO, only the surface of the structure is meshed. as a result, there is no 'region' option in construction tree for me to assign a permittivity to the whole structure. Instead, I chose the imported mesh from the tree, in the…
Hello all, I'm new to HyperMesh and having a bit of trouble with my OptiStruct simulation. As a reference, I'm using this tutorial: https://youtu.be/VbCeZkMcEdc?is=ldLBxNdns2Kl8xv0 Unfortunately, with the size-to-shuffle optimization, I'm running into this error: Attached are all the output files and the .fem file. Can…
Hi everyone, I’m working on a small FEM project in HyperMesh (OptiStruct) on a gear pump's shaft. The problem is how to properly apply the gear forces in order to get results that make sense and that it remains stable when refining the mesh. What I tried: Pressure on 3 gear teeth flanks (the gear has a total of 12 teeth).…
I have gradually built the model according to the case of MV-1029, using PointToDeformableSurfaceContact for contact, but the ball and deformable surface seem to have no contact and have penetrated directly; Later on, I changed it to 3D contact and chose the contact between the ball and the deformable surface. However, the…
I need to change the lateral friction coefficient of the tire. I modified the .tir file, but the change didn’t have any effect. I’m not sure what the correct procedure is to apply these changes.
The sketch tool "import entities" Unable to project edges to the sketch plane. It only works when selecting faces.
Description: PSIM 설치를 위해 2026PSIM 설치프로그램을 설치하면 15,40 에러가 뜨고, 안내받은대로 라이센스매니저를 설치하면 라이센스파일을 넣으라고하는데 예전에 쓰던 라이센스는 그냥 알테어 아이디와 비밀번호로 사용했어서 따로 라이센스 파일이 없어요 Product/Topic Name : PSIM
안녕하세요 기존 학부 이메일로 만든 알테어 계정이 잠김 처리되었는데 이 계정을 다시 리셋하고 싶습니다. 추가로 라이센스도 함께 리셋 가능한지 궁금합니다.
