Hi everyone! I need help getting started in this project. 1. The problem statement, all variables and given/known data I am trying to simulate the diffusion of a substance in a pipette/cell/cell-membrane geometry. 2. Relevant equations Heat Equation 3. The attempt at a solution I think the best way to tackle this problem is numerically. So is there already software out there to tackle this problem. Or do I need to write my own code in Matlab for instance?
