OptimizeBandwidth problem

[vinphend]

I wrote electrostatic model http://slil.ru/28168098 , but it stops solving it in OptimizeBandwidth section.
Any ideas how to get the solution?

ElmerGUItester is all green, Solver log is:

Hi

(~copy-paste from the old discussion list)

"Sometimes, depending on the configuration of the system and compiler, stack size may become a bottleneck in what comes to bandwidth optimization (it is a recursive task). The default linux (also other unixes) stacksizes come out very small.

If this is the case, you could try to unlimit the stack size by giving an appropriate system command (ulimit or unlimit in Linux).
using *sh (sh,bash,ksh,...) shells do:

Code: Select all

ulimit -s unlimited

using *csh (csh,tcsh,...) shells do:

Code: Select all

unlimit stacksize

If that does not help (in Windows environment) and you are using gcc/gfortran, you could also try adjusting the stack size provided by the compiler for example by defining

Code: Select all

$ export LDFLAGS="-Xlinker --stack=1000000000"

and then reconfiguring/recompiling the binaries (see gcc-manuals or more details about -Xlinker (or -Wl) and --stack). It is also recommended to use gfortran 4.2 or newer."

Also, if you recompile, consider doing so from the www.opennovation.org/ubuntu repository which has subversion r4262 vs. r4214 in the Ubuntu archive.

Thanks a lot! It helped!
