Dear All!
I have two problems with pimpledymfoam solver if I use adaptive mesh refinement (no moving mesh, just refinement and unrefinement) on OF v3.0+. First some words about the case I would like to simulate in 3D. It is a simple reaction-diffusion case in which there is a constant concentration gradient along the axis x. This gradient governs the diffusion of species A to species B and there is a reaction which converts B to A (this is why there is a constant gradient). Therefore a transient zone slowly propagates along the axis x. I planned that after testing this case, I put some difference in the physical properties of the species which will generate convection in the fluid. But now I am testing the simplest case. I have a working pimplefoam version of the solver on OFv2.2. In v2.2 I run the cases on 48 cpus but the computation is still very long. This is why I wanted to swich on AMR method. The physics and the mesh geometry are quite simple (a cuboid filled with aqueous solution with no slip boundaries at the walls) Now the two problems in short (I do not know if the problems are independent from each other or not): Problem 1: When I run the case the computation stops without any warning in the log file. CPUs still running on 100% but there are no new results written out anymore and no new notes written in the logfile. I simply solved this with writing a small script which detects this stop and restarts the computation from the last time step which was saved.
Problem 2 (and this is more weird than problem no.1.): When I run the case the computation stops but in a different way. The computation still running, there are new notes in the logfile, the results are written out but the fields (concentration, U and the others I compute) do not evolve with time. Since I have a gradient in c they should change with time as long as I have species B in the domain. The problem occurs both in parallel and single core mode. What is really interesting is that the number of iterations are really close to zero after this kind of stop (see post below).
I tried paralleltest and it ended up without error. I am so confused. I tried a lot of scenarios but the problem appeared in all of them. Please if anyone has experiences like that and comments on any of the problems feel free to reply! If you need I can send the solver and the case to try on your machine. See post #2 for attachments! Thank You! Last edited by babapeti; February 2, 2017 at 07:19. |

Hey Peter,
I am not familiar with pimpleDyMFoam or adaptive mesh refinement. But the only times where a sudden crash without any signs in the logfile happened to me where when I didn't have enough disk space to write the next time step. Probably thats not what happend here, but I thought its worth a try Cheers, Mona |

Dear Mona,
Thanks for your reply but unfortunately I have plenty of space on the hard drive. Thanks again, Peter |

hello, i am trying to simulate flow around a propeller, i create two mesh for stationary and rotary region and export them to openfoam,
then i merged them, after mergein i splte the final mesh for determain the rotary domain in dynamic mesh dict, when i try to run the case i saw the below error, how i can solve this problem thanks Create time Create mesh for time = 0 Selecting dynamicFvMesh solidBodyMotionFvMesh Selecting solid-body motion function rotatingMotion Applying solid body motion to cellZone region0 PIMPLE: no residual control data found.
