Start values in PDETime_massFlow #44

Closed marcusfuchs closed 8 years ago

marcusfuchs commented 8 years ago

In one of my applications, I see significant speed-ups for initialization and simulation just be setting start=0 for tau, inp_a and inp_b in PDETime_massFlow. I'll push this to a branch and will issue a PR. If this has no negative effects for anyone else, I think this is a useful improvement.

I was just thinking about the same, since I always get a warning that this value is not initialized and hence set to 0. Maybe it would be more logical, at least if a starting value for the mass flow is known, to set tau to length/v, but I guess the proposed solution is more than adequate.
