Hello, I am having some trouble getting a workable convection coefficient on a reactive chemistry model with a vector velocity. I have reviewed several examples from the FiPy mailing list and tried several of the variations listed there. Originally, I was receiving the error that a coefficient must be a vector. Now I seem to be getting an error that says the index is out of bounds. Specific traceback is shown below, along with the code attachment.
Could anyone suggest what I am doing wrong and how to fix it?
I'm relatively new to Python and FiPy, specifically, so please bear with me
as I am learning.
Thank you all!
