Sure. With the GUI, select File->Export, enter a .msh filename, then select the format you want in the dropdown menu. Then use File->Save Options as Default. This will save your options in ~/.gmsh-options. See also FAQ 17 in http://gmsh.info/doc/texinfo/gmsh.html#Mesh-module-questions: ``` How can I save a mesh file with a given (e.g. older) MSH file format version? • In the GUI: open ‘File->Export’, enter your filename.msh and then pick the version in the dropdown menu. • On the command line: use the -format option (e.g. gmsh file.geo -format msh2 -2). • In a .geo script: add the line Mesh.MshFileVersion = x.y; for any version number x.y. You can also save this in your default options. • In the API: gmsh::option::setNumber("Mesh.MshFileVersion", x.y). As an alternative method, you can also not specify the format explicitly, and just choose a filename with the .msh2 or .msh4 extension. ``` Christophe > Kind regards, > Randal > > _______________________________________________ > gmsh mailing list > [email protected] > http://onelab.info/mailman/listinfo/gmsh — Prof. Christophe Geuzaine University of Liege, Electrical Engineering and Computer Science http://www.montefiore.ulg.ac.be/~geuzaine _______________________________________________ gmsh mailing list [email protected] http://onelab.info/mailman/listinfo/gmsh
