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.

Hide all entities, if General. This is the Gmsh Reference Manual for Gmsh 4.
User-defined macrosUp: Plugin ModulusPhase is executed in-place. With the OpenCASCADE kernel additional expression s can be provided to define a full ellipse 4th and 5th expressions define the radii along X and Y or en ellipse arc next 2 expressions. Creates a cubic BSpline. Enable mouse selection Default value: Plugin CutParametric creates one new view.
Plugin ExtractElements creates one new view.
Gmsh – Wikipedia
Returns a value in [-Pi,Pi]. The expression-list should contain three expression s giving the X, Y, and Z coordinates of the center of the homothetic transformation. Fillets volumes first list on some curves second listusing the provided radii third list. This gmsy for example to resize the graphical window in a script, or to interact with animations in the script and in the Xocumentation at the same time. This list of arguments can also be provided in between brackets, instead of parentheses.
GetDP: a General Environment for the Treatment of Discrete Problems
Z position of light source 1 Default value: This appendix lists all the available options. Note that the following general syntax rule is followed for the definition ddocumentation geometrical entities: Structured gridsPrevious: Vertical position in pixels of the upper left corner of the graphic window Default value: Once loaded into Gmsh, scalar fields can be displayed as iso-value curves and surfaces or color maps, whereas vector fields can be represented either gmsb three-dimensional arrows or by displacement maps.
The node ordering of a higher order possibly curved element is compatible with the numbering of low order element it is a generalization. For the 2D text objects, the two first expression s in list-of-coords give the X-Y position of the string in documfntation coordinates, measured from the top-left corner of the window.

Material shininess exponent between 0 and Default value: This method works with all the algorithms implemented in the mesh module. The plugin gives an error if the eigenvectors are complex.
Rocumentation light source 2 Default value: You will then be asked to select a list of points, and to type e to finish the selection or q to abort it.
Force mesh of curves on the left-hand side slaves to match the mesh of the curves on the right-hand side masters. Copying conditionsPrevious: Plugin Probe creates one new view. Disable interactive dialog windows in scripts and use default values instead Default value: The first expression-list should contain three expression s giving the X, Y and Z direction of the rotation axis; the second expression-list should contain three expression s giving the X, Y and Z components of any point on this axis.
OptionsFileName files by hand. This allows the height of the last layer to vary along with the size of the source elements in order to achieve better element quality. Sets number of elliptic smoothing steps for the surfaces listed in expression-list smoothing only applies to transfinite meshes at the moment. Clip whole elements Default value: Minimum Y-axis forced value Default value: The difference between regular post-processing options see Post-processing options list and post-processing plugins is that regular post-processing options only change the way the data is displayed, while post-processing plugins either create new post-processing views, or modify the data stored in a view in a destructive, non-reversible way.
Background color Default value: Compute the finite difference gradient of Field[IField]: This integer is used for detecting if the computer on which the binary file was written and the computer on which the file is read are of the same type little or big endian.

They have to be given either in the GUI or on the command line see Running Gmsh on your systemand Command-line options.
