The only drawback is that you must configure and install an interpreter in addition to Gmsh for C++, C, or Fortran, or compile your code for C++, C, or Fortran. The Gmsh API (see Gmsh application programming interface) in the language of your choice (C++, C, Python, Julia, or Fortran) provides even more flexibility for more complex geometries. Thanks to user-defined macros, loops, conditionals, and includes (see User-defined macros, Loops and conditionals, and Other general commands), the built-in scripting language may easily express simple and/or “repetitive” geometries. Installing and running Gmsh on your computer Silent Features of Gmsh-:.

The next section includes a brief summary of each of the four modules, a list of Gmsh’s strengths (and weaknesses), as well as instructions on how to install and use Gmsh on your machine. The tutorial source files, as well as many other examples, are available in the source code repository. Gmsh is composed of four modules (geometry, mesh, solver, and post-processing) that can be accessed via the graphical user interface, the command line, text files written in Gmsh’s own scripting language (.geo files), or the C++, C, Python, Julia, and Fortran application programming interface.įor a high-level overview of Gmsh, see this general presentation, and the reference manual for the complete documentation, which includes the Gmsh tutorial. Its design goal is to provide a meshing tool that is fast, light, and easy to use, with parametric input and versatile visualisation features. Gmsh is a free and open source 3D finite element mesh generator with a CAD engine and post-processor built in.
