An strange error in rhoPimpleFoam
 

what means this error?

Starting time loop

Courant Number mean: 0 max: 0
deltaT = 6.719999946e-06
Time = 6.72e-06

diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0

DILUPBiCG: Solving for Ux, Initial residual = 1, Final residual = 2.359887339e-06, No Iterations 8
DILUPBiCG: Solving for Uy, Initial residual = 1, Final residual = 2.536096983e-06, No Iterations 8
DILUPBiCG: Solving for h, Initial residual = 0.9951032921, Final residual = 5.007635648e-06, No Iterations 13
word::stripInvalid() called for word r
For debug level (= 2) > 1 this is considered fatal
Aborted

for other users:this type of error return usually to the name of folders that contains the folder of case,maybe a space in name,...
