Brazilian_beginner Posted May 20, 2014 Share Posted May 20, 2014 Hello!The GWB is really an amazing tool! I have some experience with PHREEQC and PHT3D (Modflow) and am now exclusively using the GWB . I am simulating reactive transport of toluene with x2t package. The simulated biodegradation occurs by reduction of Fe (III) and methanogenesis pathways... I'm using first order kinetics to be similar to the calibrated simulations of non-reactive transport with MT3DMS.Forgive me if this subject has already been addressed, but I not found in this forum.The problem is that when you increase the value of the kinetics, the simulation not converges. If I keep a value where the kinetic model converges and increase the size of the domain, the model also not converges.Because of this, I believe the first order kinetics has convergence problems for very low values of toluene. It is possible, I established that the kinetics of biodegradation occurs only values above 0.000001 mg / l for example in the simulation? I appreciate all the help.Best regards!
