Hi all,
The follow-up on this has been quite slow due to a server room upgrade
but I have managed to rerun the problem again with the latest version of
Netgen thanks to Christophe. These runs take three or four days so are
quite slow especially with slow cpu's.
The memory error seems to have re-occurred in a different section of
code. I attach the gdb output for the following command.
gmsh box3d.geo -3 -bin -algo front3d -optimize_netgen -smooth 5 -clscale
1.0 -rand 1.e-8 -o box_c_gmsh_svn.msh
Additionally I have also run with Delaunay instead of frontal to see if
this is different. The output is below as well for this command.
gmsh box3d.geo -3 -bin -optimize_netgen -smooth 5 -clscale 1.0 -rand
1.e-8 -o box_c_gmsh_svn.msh
It seems both methods of meshing have different errors when meshing
large meshes. It seems from the gdb output the error occurs when
allocating more memory. However I also monitored the memory usage which
did not exceed 27% of the server unit therefore I imagine something
tried to allocate more than the system has in one go, possibly due to
faulty allocation request . I find the value s=18446744072204065817
being passed to DynamicMem a little suspicious.
Could somebody suggest the best way forward as we are very keen to
overcome this problem.
Thanks
Andre

Hi Christophe
Thanks for the update, have recompiled and awaiting the output. Will update
shortly.
It would be great to hear of anyone who has achieved meshes larger than 80
million elements. We are currently looking to find a limit for some very large
CFD calculations.
PS : have you tried the Delaunay algorithm?

Hi Andre,
Can you try recompiling? I have updated the version of Netgen used in Gmsh to
the latest SVN.
Thanks,
Christophe

Hi all,
I have been using Gmsh for many years and found it to be a great program. We
are now expanding our calculations and now require bigger meshes but have
started to find this to be a problem when meshing (using netgen) larger than
100 million elements. Our system has adequate RAM (256Gb) but gmsh exits with a
segmentation fault, as shown below. At present we are using Ubuntu 10.04 64Bit
AMD 6100. The problem can be found with 2.42, 2.5 and svn revision 10744
versions of the code. Interestingly for some reason the latest version of Gmsh
crashes considerably sooner than the older versions.
Gmsh 2.50 and repository version were compiled using gcc version 4.4.3, Atlas
Blas with the following command:
cmake ../CMakeLists.txt -DENABLE_FLTK=0
2.42 was from ubuntu repository
The meshing command is:
gmsh box3d.geo -3 -bin -algo front3d -optimize_netgen -smooth 5 -clscale 1.0
-rand 1.e-8 -o box_c_new.msh
The box3d.geo file is very simple box with resolutions (0.002) set on the
points as can be seen below .
To help find the problem I have tried to recompile Gmsh with debugging on. I'm
not sure which flags got set.
cmake ../CMakeLists.txt -DENABLE_FLTK=0 -DCMAKE_BUILD_TYPE=Debug
and rerun Gmsh using gdb, output below:
The error seems to be generated in Netgen moveablemem.cpp which has disappeared
in the latest version of Netgen 4.9 anyway. Given that Gmsh is still using
Netgen 4.5, is it possible to link to the later version of netgen library
installed locally instead of the built-in version to see if this helps.
Thanks
Andre
