Dear Foamers,

I'm having troubles in solving a conjugate heat transfer problem with thermal radiation. The problem I'm trying to solve is very similar to the tutorial multiRegionHeaterRadiation (a problem with conduction, convection and radiation). In order to solve this problem, the view factors need to be evaluated according to the info listed in the viewFactorsDict file (obviously, for the fluid region). However, when I run the viewFactorsGen command, OF crashes, and the output of the log.viewFactorsGen is the following:

Code:
Create time

Create mesh Air for time = 0


Total number of coarse faces: 0
#0  Foam::error::printStack(Foam::Ostream&) at ??:?
#1  Foam::sigSegv::sigHandler(int) at ??:?
#2  ? in "/lib/x86_64-linux-gnu/libc.so.6"
#3  ? at ??:?
#4  ? at ??:?
#5  __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6"
#6  ? at ??:?
Segmentation fault (core dumped)
Do you have any idea about how to fix this error? I tried to change the number of the nFacesInCoarsestLevel, but it didn't help. It seems that an answer has been provided in this post, but it doesn't seem to me that this answer is well suited for my problem.

Can anyone help me? Thanks!

Dear Foamers,

Apparently, the problem I had was caused by the fact that tha variable Qr in OF4.1 has been changed to qr. Changing the names of the variables qr and qro has fixed the problem.
