Hi
often in time series models you have steep gradients at t=0 i.e. concentration at a boundary, nothing inside the domain.
Then I have noticed that using a "boundary mesh" on the c=1 (or T=cnst) boundary can help, as you do not need always the very fine mesh in the full domain (but this is very model dependent) this works fine for me with most of my diffusion driven models, such as HT and Chemistry models

Good luck
