We want to model a petridish of bacteria in a liquid medium. So the cells comsume some substances and produce others. After some time cells in regions with good food supply are going to split. So new cells are set on the dish and we carry on with the calculation using the final values of the last step as initial values of the next.
In Comsol we did not find any documentation treating this scenario. Using old values to proceed with a calculation seems not to work when you change the geometry in the mean time. Does this work with FiPy? To me it seems possible (after playing with the mesh20x20 example) to change single points in a cell variable. That would be good news for us. (Furthermore the communication with the Comsol server from Matlab is quite hard to understand and debug. Fipy is much better in this respact. Nonetheless, the Comsol Desktop is better than Comsol's Matlab interface.) Thank you! 2013/9/23 Guyer, Jonathan E.
