Hi!

Does anyone work with three-way catalytic converters?
I'm building a FORTRAN program to simulate the temperature evolution and mass transfer along the catalysat (one-dimensional modeling). My modeling is based on previous SAE papers. But I've been experiencing problems with convergenge of the concentrations at the substrate wall (Newton Method for solving non-linear system of equations).

Thank you for your time.
Carla
