This document is a tutorial on the Gmsh mesh generator. It is aimed towards complete beginners; only some ba- sic knowledge of the Linux. This list is for questions and discussions about Gmsh features, resources, bugs, and so forth. Useful links: Gmsh homepage (for documentation, downloads, etc.) . Gmsh is a finite-element mesh generator developed by Christophe Geuzaine and Gmsh website · Official Gmsh Documentation · Gmsh Tutorials by Dolfyn.

GetDP: a General Environment for the Treatment of Discrete Problems
Combines the data from all the post-processing views having the same name into new multi-time-step views. The list of all the solver options is given in Solver options list. Minimum mesh size in the direction normal to the closest curve. Evaluate Field[IField] in geographic coordinates longitude, latitude: Delete temporary files used during printing Default value: For example, to mesh the first tutorial in batch mode, just type:.
OptionsFileName 1 or per model 2 each time you quit Gmsh? Width in pixels of the generic extra window Default value: User-defined macrosUp: X position of light source 2 Default value: An alternative syntax exists for boolean operations, which can be used when it is known beforehand that the operation will result in a single highest-dimensional entity:.
Gmsh Reference Manual
Useful for creating perturbation of meshes e. Display size of normal vectors in pixels Default value: Please note that, starting with Gmsh 2. When running Gmsh interactively, changing an option in the script file will modify the option in the GUI in real time.
Combines the data from all the post-processing views into a new multi-time-step view. Useful to compute the boundary of a complex part.
Post-processing pluginsPrevious: Executes the plugin string. Post-processing view name prefix for the results. Copy all the options from the first expression -th post-processing view to the second one. Character expressionsUp: Zero or negative tags are reserved by the system for special uses: The specification of any input to these modules is done either interactively using the graphical user interface, in ASCII text files using Gmsh’s own scripting language.
Format see General options list.
Plugin Distance creates a new distance view and also saves the view in the fileName. Views can have diffrent number of time steps Warning: Y-axis translation in model units Default value: Vertical position in pixels of the upper left corner of the option window Default value: Default color scheme for graphics 0: The operators operator-unary-leftoperator-unary-rightoperator-binaryoperator-ternary-left and operator-ternary-right are defined in Operators.
Plugin ExtractEdges extracts sharp edges from a triangular mesh. Scales all elementary entities in transform-list by a documntation expression. Node orderingPrevious: Creates a parametrization for curves and surfaces that do not have one i.
All the post-processing options can be accessed either interactively or through the input script files.
Homology and cohomology computation in finite element modeling. The value of this field is VIn inside a frustrated cylinder, VOut outside. Sub-elements are created in the new model polygons in 2D and polyhedra in 3D and border elements are created on the zero-levelset. StrCmp returns the length of the string. The various real-option s are listed in Options. gsh
You can skip most of this reference manual if you only want to use Gmsh at the first level i. Legacy formatsUp:
