Hello everyone on cfd-online!
I have some issue about my 'chtMultiRegionFoam' case and post here cause, i couldn't find how to fix in similar case. if someone solve these error, i apologize. First,below is my case and logs. https://drive.google.com/drive/folde...Pe?usp=sharing my case has 3 regions of 1fluid and 2solid. i wanna solve a heat transfer between air to fin-tube heat exchanger and refrigerant. i decided solve refrigerant as a solid to ease. the error cause when i start chtMultiRegionFoam After reading thermophysical properties, analysis will down suddenly like below. *** Reading solid mesh thermophysical properties for region Ref44 Adding to thermos Selecting thermodynamics package { type heSolidThermo; mixture pureMixture; transport constIso; thermo hConst; equationOfState rhoConst; specie specie; energy sensibleEnthalpy; } Adding to radiations Selecting radiationModel none Adding fvOptions [66] #0 Foam::error: ![]() This is my first post, so I apologize for any rudeness. |

Hello
Your job seems to have stopped due to the occurrence of "KILLED BY SIGNAL: 8 (Floating point exception)". So I have examined your 0 directory. As a result, you have set the values of p and p_rgh in relative pressure. If you use "chtMultiRegionFoam", use absolute pressure. That is, the atmospheric pressure is 101325 [Pa]. Will your job still stop if modify this?

Thank you for your advice!
I overlooked important things! There still is a problem with the stability of the analysis, but the issue was solved! https://drive.google.com/file/d/137K...ew?usp=sharing |
