Hello,
I'm making first attempts with heat transfer via radiation and started with a quite simple case comprising two plates. One acts as a source and one as a sink.
Unfortunately, the calculation stops during computation of the radiation factors for heat transfer (see SolverLog.txt attached).
Can somebody help?
Best regards
-Carsten

Re: Error during computing radiation factors for heat transfer
Could this be the same situation as in viewtopic.php?t=5846 ?

Hello,
I downloaded your files, and changed the third line in case.sif from Mesh DB "." "." to Mesh DB "." "plates3".
I added the file ELMERSOLVER_STARTINFO containing 'case.sif'.
elmergrid 8 2 plates3 -autoclean
elmersolver
It ran to completion with the results shown in the picture.
Rich.

Re: Error during computing radiation factors for heat transfer
ELMERSOLVER_STARTINFO containing the name of the sif file is a requirement for calculating radiation factors, but not for other Elmer solver runs.

Dear Rich, dear kevinarden,
I followed the instruction from Rich and now the calculation works well.
Thanks a lot for your support.

Hi,
ViewFactors has not used the command-line argument that has been available for ElmerSolver for many years. Just fixed it so it should work better in the future.
