Remeshing and code speedup

2018-07-23 Thread Carsten Langrock
Hi, Thanks for the help with getting FiPy running under Linux! I am trying to re-create a 1D nonlinear diffusion problem for which we have C++ code that uses the implicit Thomas algorithm based onĀ  J. Weickert, B. Romerny, M. Viergever, "Efficient and Reliable Schemes for Nonlinear Diffusion

Hello Dr. Wheeler, 'dx' is actually the thickness of the thermal contact region. It is not the volume of the cell. If it were a volume, the ratio dx/mesh._cellDistances would not be dimensionless. I was seeking a thermal contact region of zero thickness (dx=0), giving a true thermal contact res
