I tried to find the Cd of truck (external flow). The message always showed : turbulent viscosity limited to viscosity ratio of 1.000E+05 What does it mean? My simulated result is fault?

this means that you have problems in convergence. lots of times i have seen it but after some iterations it your case you have AMD divergence error?IF YOUR PROBLEM CONVERGES THERE IS NO PROBLEM WITH THAT IN THE FIRST ITERATIONS.

Agree with STK. You may find where the turbulent viscosity is over the limit and check if the quality of your grids is good there.
