Elliptic, structured grid generator for simply connected domains with real topography:
(Created in 2011. Posted on GitHub in 2020)
##MPI version: Open-MPI 4.1.0 compiled from source with gcc-9
>> ./configure --prefix=/MY/PATH/TO/openmpi-4.1.0/build_gcc9/ CC=gcc-9 CXX=g++-9 F77=gfortran-9 FC=gfortran-9
>> make -j 6 all
>> make install
Tested on Mac OS X and multiple versions of Ubuntu using gcc-4* and later and ifort 8.1
*Compile
cd MMesh3D
>> make
*Run
cd MMesh3D/runs
>> mpirun -np 4 ./MMesh3D.a Input_meshparam.inp
*Run with GDB debugger: First make sure that you have the proper debug flags activated in your compilation flags (-g and others)
>> cd MMesh3D/run
>> gdb --args ./MMesh3D.a Input_meshparam.inp
>> (gdb) run
*Visualization
MMesh3D generates a VTK file that can be visualized with ParaView or VisIt.
NOTICE: The PDF manual is for V1.0 and still works with the current V2.0 that is in this repo. However, it does not contain information on the elliptic smoothing. I will post instructions as soon as I have some spare time.
MMesh3D is a free and open source software according to the Free Software Foundation under a GPL license which permits any use or modification of MMesh3D as long as any derived work is open-source and preserves the same terms. For commercial, closed-source use, such as distributing a binary executable without the source, contact me directly to discuss options.
It fulfills the definition of Open Source as per the OSI definition: https://opensource.org/osd

"Only MMesh3D provides development and testing setup information.
The developer indicates that MMesh3D has been installed
without problems on Mac 10.5.4 and Ubuntu 8.10 with gcc version
4.3.2. The other software products do not provide this information,
so other developers or potential users cannot be certain that their
results are reproductions of the creator’s original results" [Smith et al. 2016]
