hi,everyone,i am a new openfoam user. I am running the sprayFoam case, where i implement the specie C12H26. I have changed the chem.inp and therm.dat. But when the case runs a few steps, it cracks. It stopped at 0.00151s.The error is like below:
Courant Number mean: 3.71158e-05 max: 0.0695979 deltaT = 1.25e-06 Time = 0.001515 Solving cloud sprayCloud --> Cloud: sprayCloud Added 6 new parcels [6] #0 Foam::error: ![]() [6] #1 Foam::sigFpe::sigHandler(int) in "/usr/apps1/openfoam-2.1.0/OpenFOAM-2.1.0/platforms/linux64Gcc44DPOpt/lib/libOpenFOAM.so" [6] #2 __restore_rt at sigaction.c:0 [6] #3 __ieee754_exp at interp.c:0 [6] #4 exp in "/lib64/libm.so.6" [6] #5 Foam::LiquidEvaporation<Foam::ReactingCloud<Foam:: ThermoCloud<Foam::KinematicCloud<Foam::Cloud<Foam: :SprayParcel<Foam::ReactingParcel<Foam::ThermoParc el<Foam::KinematicParcel<Foam: ![]() [6] #6 void Foam::ReactingParcel<Foam::ThermoParcel<Foam::Kine maticParcel<Foam: ![]() ![]() ![]() ![]() ![]() ...... Is there anybody who can help me? I guess it should be caused by particle or parcel parameters set in spraycloudProperties file, so I attached it. It can be open by word. Thanks ! |

Greetings Conceptone,
An M$ Office Word file? Are you serious? Why didn't you attach the normal "spraycloudProperties" file? Perhaps packaged in zip format? Lucky you that LibreOffice can open this blasphemous file format ![]() Anyway, ranting aside: the error indicates that something went wrong when doing an exponential calculation, namely using "exp": Quote:
The solution - use divide-and-conquer:
Bruno PS: to close the loop on this thread, it looks like this was initially being followed here: http://www.cfd-online.com/Forums/ope...d-new-gas.html

Oh by the way is it true that if I want to run the debug version the openfoam should be installed on my own computer? I mean my openfoam is installed on the service computer, so I can't modify the bashrc file since I don't have the managing right.

You can easily do your own personal build of OpenFOAM - just follow the instructions: http://www.openfoam.org/download/source.php
As for the debug build, here's an old thread on this subject: http://www.cfd-online.com/Forums/ope...oam-1-6-a.html - and yes, you'll only need to build the debug version on your personal installation!

Thanks man!I tried the source pack from http://www.openfoam.org/download/source.php
But it seems it is only for version 2.1.1 while mine is 2.1.0 because when I type in source command "source $HOME/.cshrc" I got the error message from Linux: elephant 166% source $HOME/.cshrc /usr/apps1/openfoam-2.1.0/OpenFOAM-2.1.1/bin/foamEtcFile: Command not found. /usr/apps1/openfoam-2.1.0/OpenFOAM-2.1.1/bin/foamCleanPath: Command not found. /usr/apps1/openfoam-2.1.0/OpenFOAM-2.1.1/bin/foamCleanPath: Command not found. /usr/apps1/openfoam-2.1.0/OpenFOAM-2.1.1/bin/foamCleanPath: Command not found. /usr/apps1/openfoam-2.1.0/OpenFOAM-2.1.1/etc/config/settings.csh: No such file or directory So is there any version for 2.1.0? |

Hi Bruno, the linux system manager has helped me to build the debug version(it seemed that it's not gdb) so I am not sure where should I find the so-called detail debug information. So I copy the message from log.sprayFoam file, can you help me about the error? Thanks.
