Hello all,
I am trying to run a simulation with the pimpleCentralFoam solver but the simulation stops before it really can start and I can't really figure out why. The log file shows this: Code:
Build : 4.1 Exec : pimpleCentralFoam Date : May 27 2018 Time : 12:37:25 Host : "ThinkPad13" PID : 3780 Case : /mnt/c/Projektarbeit/20180502 nProcs : 1 sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster allowSystemOperations : Allowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0 PIMPLE: no residual control data found. Calculations will employ 3 corrector loops Reading thermophysical properties Selecting thermodynamics package { type hePsiThermo; mixture pureMixture; transport const; thermo hConst; equationOfState perfectGas; specie specie; energy sensibleEnthalpy; } Reading field U Creating field kinetic energy K I also tried to use sonicFoam but there something similar happens. I don't really know what to do since there is no obvious error to fix. Does anyboady has any ideas? Greeting and thanks in advance, Sebastian |

Hello Seb,
i've the same problem with rhoPimpleFoam, Could you solve your case? I hope your answer. Thanks |

From my experience, with other solvers, when the solver stops before starting any loop the problem lies with the variables. In your case your solver can read U, does calculate K, and crashes with the next variable. So fingure out what variable comes next. Are all BC defined? Do you use the correct schemes and solver settings?

I had a similar issue, and the problem was using subsonicSupersonicPressureOutlet from libcompressibleTools of301 in of6, as I have not noticed that this and other special boundary conditions are not ported in libcompressibleTools of6-dev branch.
Is there an intention to have those in of6-dev branch as well, or they are abandoned for newer versions? Thanks a lot. |

Hi,
I plan to port compressibleTools to OF6, but maybe at latest days of December.
