[RESOLVED] Heat exchanger issue.« Back to Questions List
Hello again. I'm having an issue on my heat exchanger. solver.log have this:
Pstream initialized with:
floatTransfer : 0
nProcsSimpleSum : 0
commsType : nonBlocking
polling iterations : 0
SigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).
fileModificationChecking : Monitoring run-time modified files using timeStampMaster (fileModificationSkew 10)
allowSystemOperations : Allowing user-supplied system call operations

Turns out it was a ram issue. 16 gigs of ram wasnt cut out for a complex hx model i guess. |

I’m sending the logs and the mesh. I’m aware that my mesh is not completely legal at the moment. I was just trying to get an idea about the design. https://drive.google.com/open?id=1vHlc1f0wtGvnhb7M3lz2F4ELidy-9kqK |

Send the mesh.log in a reasonable format, so I can hopefully check. |

I suspect my geometry is far too complex and eats up all my ram. I’ll try a simpler mesh. |

Hi, the message tells you that there is no cell zone for the heat exchanger. This could have a few different reasons. |

Ah posting it like that was clearly a mistake. Lemme give you the complete log on gdrive: https://drive.google.com/open?id=1bpt-v80hvuB_-nMiTKRGOPzcg8r3CDs_ |
