Hello, I am trying to create a relatively simple thermomigration model in FiPy for a final project in my Kinetics class and have been using a paper titled Diffusion Under Temperature Gradient as a reference. I can get my system to converge and segregate if I assume constant values for the Chemical Mobility and Mobility of Thermotransport but am having convergence problems when the mobilities become functions of temperature and composition. I think my code is right but the problem is that I am using unrealistic values for the parameters not explicitly listed in the paper. Could you provide the thermodynamic system parameters you used and maybe a workflow for the code so I can check with my work? Any help would be greatly appreciated and thank you in advance for your response.
Regards, Luke Johnson
