[Archive] problems with time and dt of the standard log console

Message by Pablo Promenzio:
I am new using SPIS and when i run a simulation in a LEO environment i have a problem with the time and the dt that appears in the standard log console. The problem it that those values are too small, so when i try to run a simulation of 1000 or 5000 seg it never ends or conrverge. What are the parameters that i have to put to handle the time and the dt??
I have set up this global parameters for leo environment
flag linear poisson equation=0 (because of the small Debye Lenght)
flag electric circuit integrate=1
flag fixedt=1
Can anyone tell me if that it is correct for LEO, please? Or what are the others parameters that i have to set up in the global parameters. I have set up the electron and ion densities and temperatures for that environment only, but i need the other parameters too, please.
Best regards, Pablo
