Hi there!
Apologize for this silly question. A lot of people had the same issue in the past but all the topics i've read did not bring me to any valid solution. I have to estimate the Reynolds stress tensor from a KomegaSST time variant compressible simulation (rhoPimpleFoam) whose results are saved on my laptot. I'm currently using OpenFOAMv10. Following this guide: https://www.openfoam.com/documentati...nceFields.html i modified my /system/controlDict as follows: Code:
turbulenceFields1 { // Mandatory entries (unmodifiable) type turbulenceFields; libs (fieldFunctionObjects); // Mandatory entries (runtime modifiable) // Either field or fields entries fields (R devRhoReff); field R; } Code:
rhoPimpleFoam -postProcess -func turbulenceFields Code:

Hello,
You have several things mixed up. Lets try to clarify. When you are using this command: Code:
rhoPimpleFoam -postProcess -func turbulenceFields When using this predefined function, you need to pass the list of fields you want to process as an argument. This is why you are getting this message in your log: Quote:
Code:
rhoPimpleFoam -postProcess -func "turbulenceFields(R devRhoReff)" Code:
rhoPimpleFoam -postProcess I hope this helps, Yann |

Hi Yann,
Apologize for my late reply. I have been very busy lately. I hope i'm not doing necroposting. Thank you so much for your reply. Yeap, you gave me a precious hand to clarify several concepts. One last question then i close the topic: in your opinion is better to recover the R stress tensor starting from a K-epsilon or a K-omega simulation (same mesh, same BC, etc..)? Should it be the same? Thank you very much. |
