I use comsol 5.1 for modeling NOx reduction. the model has been solved but, radial velocity profile isn't correct.
the model is steady or transient? and a doubt: why do you have a radial velocity profile if you have a PFR???
Repeated error test failures. May have reached a singularity.Undefined_value_found_during_constraint_handlingLast time the step is not converged.
