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...) 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.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.
