Running Radiation model in parallel
 

Dear All,

I am setting a case with 10 solid and one fluid regions to investigate conjugate heat transfer in this problem. I am going to solve this case with ChtMultiREgionSimpleFoam.
The case has been launched without problem in serial and parallel when I neglected the radiation , but when radiation is considered, I have got the error in parallel run.

As suggested in and old thread ( https://www.cfd-online.com/Forums/op...-parallel.html ) After decomposing the domain with , for instance 2 cores, I launched the faceAgglomerate and viewFactorsGen in parallel like:

mpirun -np 2 faceAgglomerate -region air -dict constant/viewFactorsDict -parallel
mpirun -np 2 viewFactorsGen -region air -parallel


but I still got the following error:


Do you have any idea how to solve this problem?
The error is not clear and I can not understand where the problem is?
