Good evening, Thank you very much for the reply. Indeed, the use of the Butcher tableau for constructing RK methods is very convenient. This discussion was very helpful, so I would like to thank again Dr. Bangerth and Dr. Turcksin for their quick responses. Regards, Aslan On Sunday, November

Dear deal.ii team, I am currently at the stage of choosing a transient solver for our deal.ii-based software OpenFCST. The solver will be applied to solving nonlinear transport and reaction problems. After days of research, I found two options: 1. Variable order, variable step BDF schemes (
