Tutor on COMSOL reacting flow in porous media interface

I need you to develop some software for me. I would like this software to be developed for Windows . The development of a model in 2D axisymetric and Reacting Flow in Porous Media (Transport of Concentrated Species) Interface is ongoing. An expert's insight is needed to analyze the model-in-progress to help address the underlying problems in the model. Good understanding of COMSOL Reacting Flow in Porous Media (Concentrated Species) interface is required and understanding of the Sievert's law boundary condition in chemical engineering. Your primary task is teaching COMSOL Reacting Flow in Porous Media (Concentrated Species) interface and the process of including the Sievert's law boundary condition for a membrane. Ideally this will be done via online video session using skype and COMSOL version 5.3. Fluent communication in English is required.
