Dear OpenFOAM users

I'm using OpenFOAM-1.4.1_patched (incl. patches till end of january) and compiled for 32- (Intel Pentium M processor 2.13GHz stepping 08) and 64-bit (2 AMD Athlon 64 X2 Dual Core Processor 5200+ processors) x86 environment.

When I run the tutorial case "damBreak4phaseFine" using the following commands:

$ run
$ cd tutorials/multiphaseInterFoam
$ blockMesh . damBreak4phaseFine
$ multiphaseInterFoam . damBreak4phaseFine

i get the following error (at the indicated timestep):

Courant Number mean: 0.048008 max: 0.488295
deltaT = 0.00158513

#10 Foam::regIOobject::readIfModified()

Please note, that this sigFpe occurs on both architecturs but when I try to run it on MAC OS X (running a port of OpenFOAM-1.4.1_patched) the problem occurs not that early in the calculation.

Could somebody please comment on that? I'm using openSUSE 10.3 with gcc-4.2.1, flex++ 2.5.33, etc.

Thanks a lot for any help!
