Has anyone used surfaceToPatch
Hi,
I generated a mesh. Unfortunately, it only has 1 patch. I need to split this one patch into several patches (inlet, outlet, wall,..etc.). Has anyone here tried surfaceToPatch utility? Supposely, it can read in a surface file and then, patch the faces ontop of the surface read. What type of surface file does it read? stl? Or can it be I-DEAS unv file (this will be a 3D shell mesh I think). Thanks! Pei |
Hi Pei,

Hi Pei,
Doesn't autoPatch help you? What about the gui patchTool? Dragos |
Hi, Dragos,
I have not used
Hi, Dragos,
I have not used either autoPatch or gui patchTool before. Is gui patchTool part of FoamX? I usually do not use FoamX. Also, autoPatch may not achieve what I want. Let me explain: I have a complex geometry. The mesher reads stl surface in, then, mesh the geometry - NO surface information kept in the mesh generated. However, I can use my CAD software to only export the surface patch interested (say an inlet face) to a second stl file. I am hoping the surfaceToPatch can read this second stl file, then, searches through the boundary faces, save the faces that "belongs" to the stl face, AND then, created a new inlet patch in OF format. I am reading the surfaceToPatch source code now - just curious how it works before I understand the source code. Pei |
Hi Pei,
autoPatch will genera
Hi Pei,
autoPatch will generate automatically a patch for every surface on your mesh. patchTool runs separately from FoamX and will let you pick visually the surface you need. Then will generate the patch in a boundary file. But now you made me curious about the surfaceToPatch which seems more apropriate for complex geometries with many different boundaries. I'll take a look at it too. Please let me know about your findings. Dragos |
Hi, Dragos,
autoPatch split
Hi, Dragos,
autoPatch splits external faces based on user specified angle. I remembered now that I tried it few times in the past and I was not able to get the patches I wanted due to curved/complex surfaces. I was not able to find any info on gui patchTool. How can I start it? When reading the second stl into surfaceToPatch, I got errors. I might need to convert the triangulates in stl to something surfaceToPatch can understand. If I can just get surfaceToPatch to split the boundary faces based on the stl file, then, it will be really cool. Pei |
