![]() I was hoping using a STEP file might improve upon this.ģ. The reclassified mesh seems to retain these irregularities. I attempted to follow similar steps as those from the post, however the STL file seems to have a number of irregular shaped triangles that I would like to avoid having in my mesh. I may possibly post the question there as well. I have also subscribed to the Gmsh mailing list. I have had a look at the post you linked. Therefore, I thought Gmsh might be a better tool to accomplish this.Ģ. All of this will be need to be done with little to no human interaction. This is because I will need to be able to construct new geometries parametrically, mesh the new geometries, and then evaluate them. I have thought about using sHM, however the nature of the bigger problem really requires a parametric meshing tool. Thank you for taking the time to respond to my post.ġ. I will be sure to post progress here so that my post may have future use to others. I am sorry if any of these questions come across as trivial, I am new to Gmsh and unfortunately have not found much online about using Gmsh for STL/STEP files. I attempted to upload the STL files, however they even after zipping, it was too large.įurthermore, if I would like to use Gmsh to define all the different surfaces of the geometry (so that patches can be defined readily in OpenFOAM), how might I go about doing this using a geo script? Is it best to merge the STL/STEP files individually (as this would presumably allow for patches to be defined more easily) or should I initially merge all the files into one volume? I can use FreeCAD to do so if that is indeed the better option. The end goal is to use this mesh with OpenFOAM to simulate internal flow through the volute.Īfter some previous research online, it seems that it might be best to initially convert from STL to STEP. The STL files define a centrifugal pump volute with inlet, outlet, and wall. Meshing 3D volume from STL/STEP Files (Gmsh) - CFD Online Discussion ForumsĪs the title says, I am trying to use Gmsh to mesh a 3D volume that is enclosed by a number of STL files.
