![]() ![]() msh file format.Īll text after the -run is propagated to GMSH, see sample options below. fe_gmsh then outputs the model processed by gmsh, which is usually written in. All characters in the command after -run will be passed to the gmsh batch call performed. Command option -run allows to run gmsh on the written file for meshing.stl writing format is also supported, by using extension. Command option -spline can be used (when lines have been declared using command AddLine3 from beam3 elements) to write spline objects instead of line objects in the.Command option -keepContour can be used to force gmsh not to add nodes in declared line objects ( Transfinite Line feature).The default behavior will define a single Plane Surface combining all contours, while -multiple variant will declare each contour as a single Plane Surface. Command option -multiple can be used for automated meshing of several closed contours.You can also define a nodewise characteristic length by setting non zero values in model.Node(:,4). ![]() geo file which root name is specified as FileName (if you use del.geo the file is deleted on exit).Ĭommand option -lc allows specifying a characteristic length. Elt) and geometry data in model.Stack'info', 'GMSH' into a. Writeįe_gmsh( 'write FileName.geo',model) writes a model (. Readįe_gmsh( 'read FileName.msh') reads a mesh from the GMSH output format. This command also provides a good test to check your gmsh setup as the output will be empty if gmsh could not be found. Setpref( 'OpenFEM', 'gmsh', '$HOME_GMSH/gmsh.exe')Ĭommand Ver returns the version of gmsh, the version is transformed into a double to simplify hierarchy handling ( e.g. The fe_gmsh function uses the OpenFEM preference to launch the GMSH mesher. For this command to work, beam3 elements must be used, so that a middle node exists to be declared as the spline control point.įor this command, data can only be an element string selection.
