Note that the options given to configure in the example above are the minimal ones to build Gmsh with OpenFOAM support. Also, don't forget to run autoconf before running configure. Please make sure proper OpenFOAM environment variables are set up before building Gmsh because the configure script uses the environment variables to detect the gmshFoam and OpenFOAM libraries. yes <<- Indicates the detection of OpenFOAM libraries!Ĭhecking for grep that handles long lines and -e. with-foam- prefix= $WM_PROJECT_USER_DIR/applications/utilities/gmshFoamĬhecking for main in -lgmshMessageStream. configure - prefix= $WM_PROJECT_INST_DIR/ $WM_ARCH/gmsh- 2. $ patch -p1 < $WM_PROJECT_USER_DIR/applications/utilities/gmshFoam/gmsh- 2. Apply the patch included in the gmshFoam package to Gmsh sources, and build/install Gmsh. The converters should work without Gmsh.ģ. If you only need converters ( gmsh2ToFoam, foamToGmsh and foamMeshToGmsh) you don't have to take extra steps below. into $(FOAM_USER_LIBBIN): libgmshFoam.so, libgmshMessageStream.so.into $(FOAM_USER_APPBIN): gmsh2ToFoam, foamToGmsh, foamMeshToGmsh, gmshFoam (a sh script), gmshFoamMonitor.With this step the followings will be installed: $ ln -s gmshFoam-YYYYMMDD gmshFoam <<- Necessary for gmshFoam to be recognized by FoamX $ cd $WM_PROJECT_USER_DIR/applications/utilities Build the libraries and standalone utilities ( YYYYMMDD denotes the release date of the gmshFoam package). The Gmsh source package: $WM_PROJECT_INST_DIR/$WM_ARCHġ.The gmshFoam package: $WM_PROJECT_USER_DIR/applications/utilities.In the following procedure, the gmshFoam and Gmsh packages are assumed to be downloaded into: The autoconf utility that comes with your Linux distribution if you would like to use gmshFoam.gmsh-2.0.8-source.tgz: You need the source distribution of Gmsh if you would like to use gmshFoam (the standalone converters, gmsh2ToFoam, foamToGmsh and foamMeshToGmsh, should work without the Gmsh source).The gmshFoam package: Download from the Download section below.With all these considered, I'm making gmshFoam to be like a lightweight, easy-to-handle and versatile Alphajet, not an F-15 real combat aircraft. You may find gmshFoam is sometimes too slow with only ~ 100,000 postprocessing elements. On the other hand, a major downside of gmshFoam for general usage is, as the Gmsh manual states, its slowness for large-scale problems especially on postprocessing. I am also finding gmshFoam to be quite usable for solver development, where many small test cases are often run manually. The concept has been turned out to be fairly successful in that even students who had been high-schoolers until a month before can do basic works after a three-hour lecture. paraFoam, it generally requires less user interactions to do the same thing. I thought Gmsh is an excellent software to be used in company with OpenFOAM for true starters, because it contains all the necessary peripheral processing stuff in simple user interface with sophisticated graphics. GmshFoam is primalily meant to be a course material for an introductory course in computational engineering. Feel free to take over the project if you feel like to do so. NOTE: The developer had ceased the maintenance of the codes and the page is only kept for archival reason. Readers are recommended to read this page up to the final Technical section, where there are lots of footnotes and remarks, before installation. "Conceptual," or "proof-of-concept," because it is still very preliminary. On-the-fly visualization of the oodles/pitzDaily case by gmshFoam.Ī conceptual implementation of a total Gmsh pre/mid/post-processing environment for OpenFOAM.
