[Archive] Simulation dt

Message by abul anuar:
i’ve got 2 questions to ask.

  1. during the simulation, after each time step, i notice message like ' validity saturation = 0.9815999 => dt = 0.025436698 '. What does it means? Is it mean that the time step would be valid up to 0.9 sec, but the simulation only increase the time step by 0.02 sec? If that is so, how do i improve on my simulation time without having an out of memory error. How do we determined the best time step to use (could anyone give other answer than the one in the tips).
2. Where can i find the reference for the technique used to construct the PICVolDistrib? abul
