Hello foam users,


I am a new user to OpenFoam and I am running a tutorial on heatedDuct based on chtMultiRegionFoam module. I have followed all the tutorial steps and now I am stuck at the last step of running chtMultiRegionFoam. Below is the error that I get. Also, I am using OpenFoam version 10.


can anybody help me with this problem?



Thank you,

You try to write a field named volAvgHeaterT but this field name does not exist in the registry. Probably because you use a fieldFunctionObject in your controlDict that is not set up propertly. Dump the contents of this functionObject


Use the dedicated OpenFoam forum. Maybe actually follow instructions.
