If GiD recognized the new problem type, there should be an entry 'inp' in the 'Data/Problem type' menu. This is done by copying the directory '$MAGPAR_HOME/src/tools/gid/inp.gid' to the subdirectory 'problemtypes' of your GiD installation.

The installation of GiD is very easy on Windows as well as Linux platforms.Īfter the installation of GiD the new problem type 'inp.gid' should be installed. An evaluation version, which is restricted to 3000 finite elements, is available on the web for free. GiD is the 'personal pre- and postprocessor' from the 'International Center for Numerical Methods in Engineering' (CIMNE). Salome has powerful tools to generate 3D geometries (even with combinations of bottom-up and top-down approaches and tools to generate unions, intersections, cuts, etc.), mesh them, and export them in various formats.Ĭurrently, there are no converters for the FE meshes generated by Salome yet, but Gmsh can import Salome's output. It is based on an open and flexible architecture made of reusable components. Salome provides a generic platform for Pre- and Post-Processing for numerical simulations. project.inp, project.out: finite element mesh). Richard Boardman and Hans Fangohr have implemented the tool ngtoucd.py, which converts neutrally-exported NETGEN meshes into AVS/UCD files (cf. It is available for Unix/Linux and Windows. Netgen is open source based on the LGPL license. NETGEN contains modules for mesh optimization and The connection to a geometry kernel allows the handling of It accepts input fromĬonstructive solid geometry (CSG) or boundary representation (BRep) from NETGEN is an automatic 3d tetrahedral mesh generator. You can check for a bad mesh by looking at the. Au1*u1=divM in Hdemag()) do not converge. Sometimes Gmsh will generate a suboptimal mesh! This will often cause magpar to run very slowly (because the mesh structure results in larger numerical errors in the magnetostatic field, which causes the time integrator to take very small time steps) or to fail when the linear solvers (for the calculation of the magnetostatic field, e.g. The examples sphere_larmor: Larmor precession and mumag3b: mumag standard problem #3 with 2 cubes use finite element meshes generated with Gmsh.

The Python program gmsh: gmshtoucd.py (provided in the $MAGPAR_HOME/src/tools/ directory), can then be used to convert Gmsh mesh files (version 2.0) into UCD/inp files (cf. This issue has been resolved in Gmsh version 2.2.1: If this happens, it can help to increase the Linux/Unix resources - in particular the maximum number of open files - in /etc/security/nf: Sometimes, Gmsh completes the mesh generation but it cannot save the mesh. In addition, it might be necessary to tweak the ids of these physical volumes by hand in the *.geo file to ensure that these physical volumes are numbered consecutively starting from 1. In order to assign different property ids to different parts of the volume it is necessary to define corresponding 'Physical groups' (Add/Volume). The mesh is then exported using Mesh/Save or File/Save Mesh as a *.msh file.

Gmsh uses TetGen or NETGEN to generate the tetrahedral finite element mesh.

Using the graphical user interface or in ASCII text files using Gmsh's ownĪfter defining the geometry the 3D tetrahedral mesh has to be generated. The specification of any input to these modules is done either interactively

Gmsh is built around four modules: geometry, mesh, solver and post-processing. Simple meshing tool for academic problems with parametric input and
