The STEP/IGES format can be imported in GMSH using File -> Merge option. The STL geometry can be used in snappyHexMesh to generate a mesh for CFD simulation in OpenFOAM. The FreeCAD file, STEP and STL geometry can be found here: Z-Bend FreeCAD, Z-Bend geometry in STEP format and Z-Bend STL Geometry. How many of these names have you heard of? Click on the names to know more about them! In the API: gmsh::option::setNumber("Mesh.MshFileVersion", x.y). geo script: add the line Mesh.MshFileVersion = x.y for any version number x.y. In the GUI: File->Export and pick the version in the dropdown menu. Use "-format msh2 -2" command line switch while generating MSH file. As per thread on, gmshToFoam can convert only version 2 of Gmsh format. The syntax is gmshToFoam case.msh -case oFCase. The recommended method to convert a GMSH mesh to OpenFOAM format is to use utility gmshToFoam. A new variable is defined as eSize = 1e-2 and a new point can be created as Point(1) = While FreeCAD uses Python for scripting, GMSH calls its scripting language as 'affectation'. The purpose is to compile information in a place for reference to current and future users of GMSH program for learning purposes. The publisher of has not made contribution to some of the example cases included here and asserts no claim or copyright.
Though it is imperative to go though all the tutorials the way the authors of this program have designed. This will help a potential user of GMSH to directly jump to the tutorial which fits his/her requirements. The information is being updated gradually, starting with a visual description of the output from each tutorial. The purpose of this web-page is to summarize the capabilities of FreeCAD and GMSH by adding user experience while running the tutorial cases.
