Creating a mesh

Use of the platform
1

Hi everyone.

I’m new to Salome. I want to create a grid model for later use in OpenFOAM.

I used the Shape module (created a parameterized multi-region geometric model in the form of a wedge-sector).

Next, Geometry assigned names to each face. In addition, I created a group of edges for subsequent meshing.

Then, in the Mesh module, I was able to construct a grid for two of the three areas. But I can’t figure out the remaining region in the form of a wedge. My guess is that Salome doesn’t like the small number of ribs for the remaining region.

It is important for me that the grid is one cell wide.

I will attach a link to the video lesson from which I created my mesh, and I will also attach my .hdf file (Salome version 9.15).

you are assigning the wrong mesh hypothesis. what you should do is mesh the triangular face and from there extrude in the other direction. the extrusion 3D algorithm works for prisms geometries where you mesh one of the face with a submesh.

have a look at the modified Mesh_1 i make for your case.

PS. before uploading your hdf files CLEAN YOUR MESH DATA your file is 7.3 mb mine 601 kb. then you select your mesh and simply compute it again in local.

Thank you so much for your help!
Okay, now I will know about “Clear Mesh Data”
