Open source Structured Mesh Generator
Dear forum,
This seems to be a classic question, but the answers do not seem to satisfy.... "Is there an open source STRUCTURED mesh generator in the likes of Gridgen/Pointwise (dare I say Gambit..!?) that works well?" "Well" is defined as: Having a GUI Ability to generate connectors on surface geometries Export to common commercial packages and OpenFOAM Reasonably reliable (basically a pointwise clone) I really struggle with this as it seems to me (and I don't know much...:(:confused:) that it is much simpler to write a program for structured meshes rather than unstructured tet/hex meshes as there is no real algorithm in the structured. It is all user defined. But I'm sure I'm wrong, as I can't find any decent ones. The ones I've come across are: >>GMSH >>Salome >>CalculiX >>Overture Any help would be great. |
This is not open source, however, if you are U.S. citizen or permanent resident belonging to a U.S. organization you can use Chimera Grid Tools for free.

Not open source but there is Discretizer and then MegaCADs.
http://www.megacads.dlr.de/ http://www.discretizer.org/ the question why Paraview cannot create meshes has been asked but apparently its too tricky with the pipeline structure. |
Thanks a lot for the replies.
Unfortunately I don't qualify as a US citizen, but the other ones look very interesting. Now does anyone know if it is possible to convert from say discretizer to a Fluent format, say .msh? Is this an easy step or prone to errors? Many thanks guys; been a great help :) |
I have never used it, but the only thing I can think of that meets your requirements is MegaCads.
