Hi Robin,

thank you for the information, especially for the great literature source.

Your examples and the converter doxygen gave me a better understanding.

What I am trying to do is having a relatively high charU = 200m/s and a very small latticeL < 0.0001. With latticeU at around 0.3 (higher values tend to get unstable), I get very small physical time steps at 10^-7s (with physTime= latticeL*latticeU/charU * latticeTime(=1)). For my purposes I only need about 10^-5s. Is there a way to increase the time step length other than changing charU, latticeL or latticeU, because these are quite fixed in my case.
