Hi, I have seen pass by the new pipe type 'relax_disp' a few weeks ago... Since relaxation dispersion is in the list of techniques planned to be supported in the future, I guess this is the first step toward implementation... I would like to contribute to the development of this type of analysis. What first steps could I do ? Should there be a new branch created to start this ? Should some unit and system tests be written ? Should first equations be introduced ? Let me know what are your plans for this, Ed, and I'll try to help you in any way you find useful. Regards, Séb :)
