OpenFOAM remote cluster run error
Hi,
I am trying to run multiphaseInterFoam in remote cluster in parallel. I getting this error which I couldn't understand: Code:
[1] #0 Foam::error::printStack(Foam::Ostream&) in "/users/krmedam/OpenFOAM/OpenFOAM-2.4.0/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" Thanks in advance. Regards, Krishna. |
Hi Krish;
I guess there is no problem running the case on the cluster but i guess there is some sort of problem with the code. Maybe you edited the code and compiled it successfully however at some point while running the code you are hitting some function where you could be dividing with 0 thereby causing this error. Maybe, the easiest way to start is just try a simple case without modification and it should work perfectly and later edit the code stepwise. Hope this was useful; Saideep |

Thanks for the reply. I didn't messup anything with the functions of multiphaseInterFoam. Sure, I'l try your suggestion and get back to you. Thank you, Krishna. |
Hi,
If we try to decipher the error message: 1. Error happened in multiphaseMixture::multiphaseMixture 2. The error was FPE, and it happened during division. Let us check division operations in multiphaseMixture constructor: Code:
... 1. zero average density 2. zero mesh volume (yet in this case, I think, the error would be in pow function not in division operator) Provide checkMesh output, check you initial conditions. |

Thank you for the reply and sorry for the delay in response. I did check the output for checkMesh and everything says ok. Here is the output from checkMesh: Code:

Hi,
Maybe I did not get your idea right but atmosphere patch is something special: in every alpha (air, drop, and film) it has type inletOutlet (this is OK), inletValue is 0, and initial value is 0, i.e. there is no matter at this patch and it produces nothing in case of counter-flow ;) So rho there is zero, and as a result you got division by zero FPE. Since air is in contact with atmosphere initially, I have changed BC to: Code:
