Hi everybody,
I tried to run a case on 16 processors using buoyantPimpleFoam solver. I decomposed the domain according to the user's guide. And then run the case using the command: <path>$ mpirun -np 16 buoyantPimpleFoam -parallel but I got the following error: --> FOAM FATAL ERROR: bool IPstream::init(int& argc, char**& argv) : attempt to run parallel on 1 processor From function UPstream::init(int& argc, char**& argv) in file UPstream.C at line 79. FOAM aborting I have already used Foam in parallel, and am pretty sure that I've done everything correctly. Anybody has an idea what this error means?! Please help! I may lose my job!!

hi, i know it was a long post. Just to share in case others are facing it. I solved it by recheck and changing the number of domains in decomposeParDict to that of the np. I am not sure if your case has the same careless mistake
because line 79 shows this: Code:
if (numprocs <= 1) { FatalErrorInFunction << "bool IPstream::init(int& argc, char**& argv) : " "attempt to run parallel on 1 processor" << Foam::abort(FatalError); } Please correct me if I am wrong. Thanks Last edited by jiahui_93; March 13, 2018 at 04:04. |
