3D Meshing Ideas?
2 Attachment(s)
Dear Forum Users!
After completing some simple meshing tasks with gmsh (2.2.6) and discretizer, I will do some more realistic meshing cases. I have to use this old gmsh version, otherwise there is no chance for me to convert it via gmshToFoam (OpenFOAM 1.5-Dev). The next case will be a more realistic variant of my hotgas nozzle (inert gas). We have different wall temperatures and an inlet pipe, which is normal to the main pipe. Later on, I wanna take a turbulent heat transfer solver. For a better imagination, I attached two images of the 3D part (ProEngineer). For the first try I exported it as a .stl The colored surfaces represent the intended boundary layers:
My experience with snappyHexMesh is ... not the best. I dont know how to define the boundary layers and there are problems with "sharp" edges. Maybe there is a way with the discretizer... Importing the .stl in gmsh 2.2.6 works really good, but I dont have an idea how to create the 3D mesh with this version. So, do you have some ideas, how to get a mesh out of the 3D model for the upcoming case. Thanks in advance Edit: Just work around with Pointwise and updated the 3D model to be more ... fluent ;) I split the geometry in a rear part with the intersection, and a front part with the nozzle, if someone have experience with this kind of meshing, help is welcome :o |
Its going on
