Error: domain-thread-integrals: invalid thread
 

when I try to run a simulation, using k-epsilon realizable, steady state I get the following error message:

iter continuity x-velocity y-velocity z-velocity k epsilon cd time/iter

turbulent viscosity limited to viscosity ratio of 1.000000e+05 in 11304 cells

Error: domain-thread-integrals: invalid thread Error Object: 130

anybody knows whats wrong?
