Can someone help me, why I get this error during my simulation.

It seems that there is no lamd running on the host gnode1.

This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for the "mpirun" command.

Please run the "lamboot" command the start the LAM/MPI runtime
environment. See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.

Thank you in advance

Judging from the error message you have a floating point exception (division by zero or negative square root) computing the temperature dependent viscosity using the Sutherland model.

So maybe you have some negative temperature somewhere.


But this is only a guess since the details you provide are far from be enough to fully understand what's going on.

Hi Michael,

I am performing a compartment fire simulation using fireFoam solver. I am using OF v1812. My simulation is based on LES turbulence approach and EDM combustion. Actually, this is similar to the tutorial "compartmentFire" in OFv182. I created compartment walls using topoSet Dict and extrudeToRegion files. Initially, the simulation was going well, during the 20 s of simulation time I got this error. My total simulation time is 500 s.

For more detailed information I have attached my input files.

[mAlletto]

did you try to write your field right before the simulation crashes? This usually helps to find out what's going on.


If you want someone to run you case you should also include an Allrun script in order to reduce the time spent of the people which wanna help you to a minimum.

[mAlletto]

Another comment: The test case is quite big and not everybody can run it on his home computer.

Hi Michael,

Sorry for the late response! As like you said, I have arranged my input file suitable to simulate on a normal PC computer. Also, I have created Allrun file.

But unfortunately, I encountered another new problem when I tried to create a patch in my case file.

--> FOAM FATAL ERROR:
Face 8427 specified in set fBurner is not an external face of the mesh. This application can only repatch existing boundary faces.

From function int main(int, char**)
in file createPatch.C at line 740.
FOAM exiting.

could you please help me regarding this?
