Hello evreyone,

when i run my simulation i get these errormesseges:

Starting time loop

forceCoeffs forces:
Not including porosity effects

Time = 0.0001

I guess, this is a general problem, like too high/low timesteps or something?

I use pisoFoam,
Checkmesh gives me no errors,
turbulence is turned off, however openfoam wanted me to define a "k" and "omega" file, which i don't understand as well.

I already tried "deltaTs" from 0.1 to 0.0001 but this wount make much of a difference.

I hope someone has an idea or hint. Thank you in advance!
