OpenFOAM - Why Initial residual is not equal to the final residual obtained from the previous iteration in case of fvDOM radiation solver?

Why Initial residual is not equal to the final residual obtained from the previous iteration in case of fvDOM radiation solver?

Hello, I am working on fvDOM library to simulate a radiation problem. I was just wondering why Initial residual is not equal to the final residual obtained from the previous iteration? Thank you very much. Regards, Ankur

Hi Ankur, fvDOM is a radiation model used in OpenFOAM to solve heat transfer problems. Can you please tell the details of the solver you are using for your simulation to answer your query. Thanks & Regards Deepa V

Hello Madam, We are using our own solver which uses fvDOM library, which in turn using PBiCG as a matrix solver to provide the solution.
If you want, I can send you a copy of that.

Thank you very much.
