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.
