Gmsh ships prebuilt binary SDK libraries for Linux. You can make an alias for this command in your /.cargo/config file: alias tt 'test -test-threads1' Linking to the Gmsh library. Run the tests using cargo test-test-threads1. > I've included a minimal working example, where test.geo defines my "deformed" mesh (unfortunately I cannot send the mesh file directly, but I generated it just using "gmsh test.geo -2", and I want to remesh this using remesh. Gmsh is a shared resource, and Rust tests run in parallel by default, so cargo test alone will crash. > However, this does not work if I have multiple (adjacent?) surfaces in my mesh. Note that we are (again.) reworking the remeshing pipeline to make it more robust: the parametrizations will now be persistant (saved in the mesh file), and the internal workflow will make it possible to use with discrete entities all of the features currently reserved for CAD entities: mesh size depending on curvature, parallel meshing, high-order meshes, etc. You should also remove "Coherence Mesh" from remesh.geo, as the mesh is already conformal. To make it work with Gmsh 4.3, just remove the "Physical" definitions on test.geo. Note that I cannot reproduce the seg fault with the latest Gmsh version - which version do you use? Here however since you only save the triangles (not the line elements on the curves, due to your physical definitions), the 1D mesh is empty - leading to an empty surface mesh. > I would like to use gmsh for remeshing a transformed mesh (which was orignally created with gmsh) and I think that the CreateGeometry command would do exactly what I want: Take a discrete mesh and extract the underlying geometry (ideally with the same indices) so that I can perform a remeshing.ĬreateGeometry will create a parametrization of the underlying mesh, so that it can be remeshed. > I've got a question regarding the CreateGeometry command in conjunction with multiple Surfaces.
