Hello evreyone,

when i run my simulation i get these errormesseges:

Starting time loop

forceCoeffs forces:
Not including porosity effects

Time = 0.0001

Courant Number mean: 7.96332e-08 max: 1.02137e-05
smoothSolver: Solving for Ux, Initial residual = nan, Final residual = nan, No Iterations 1000
smoothSolver: Solving for Uy, Initial residual = nan, Final residual = nan, No Iterations 1000
GAMG: Solving for p, Initial residual = nan, Final residual = nan, No Iterations 1000
GAMG: Solving for p, Initial residual = nan, Final residual = nan, No Iterations 1000



--> FOAM FATAL IO ERROR:
wrong token type - expected Scalar, found on line 0 the word 'nan'

file: /home/thorbrue/CFDe/HA2/system/data.solverPerformance.p at line 0.

From function operator>>(Istream&, Scalar&)
in file lnInclude/Scalar.C at line 93.

FOAM exiting


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!
