gmsh.jl

gmsh.jl contains the libgmsh.so/gmsh.dll artifact and Julia API gmsh.jl for Gmsh: a three-dimensional finite element mesh generator. Currently, only the built-in geometry kernel is supported in gmsh_jll.jl.

All credits go to the Gmsh devs. This package only copy pasted the gmsh.jl API and used BinaryBuilder.jl and Yggdrasil to deploy the binaries.

Important: All functionalities related to GUI and OpenCASCADE are not supported by the artifacts of the package. OpenCASCADE support will be added in Future. Linux users can already utilize it by having a proper OpenCASCADE installation in their PATH.

Example

using gmsh

After that, follow the commented examples in examples. The tutorial/t1.jl from the official Gmsh repository can be realized with this package as follows:

gmsh.initialize()
gmsh.option.setNumber("General.Terminal", 1)
gmsh.model.add("t1")
lc = 1e-2
gmsh.model.geo.addPoint(0, 0, 0, lc, 1)
gmsh.model.geo.addPoint(.1, 0,  0, lc, 2)
gmsh.model.geo.addPoint(.1, .3, 0, lc, 3)
gmsh.model.geo.addPoint(0, .3, 0, lc, 4)
gmsh.model.geo.addLine(1, 2, 1)
gmsh.model.geo.addLine(3, 2, 2)
gmsh.model.geo.addLine(3, 4, 3)
gmsh.model.geo.addLine(4, 1, 4)
gmsh.model.geo.addCurveLoop([4, 1, -2, 3], 1)
gmsh.model.geo.addPlaneSurface([1], 1)
gmsh.model.addPhysicalGroup(0, [1, 2], 1)
gmsh.model.addPhysicalGroup(1, [1, 2], 2)
gmsh.model.addPhysicalGroup(2, [1], 6)
gmsh.model.setPhysicalName(2, 6, "My surface")
gmsh.model.geo.synchronize()
gmsh.model.mesh.generate(2)
gmsh.write("t1.msh")
gmsh.finalize()
