Length scale was zero

September 6, 2001, 11:22

Hi, I am doing a transient flow simulation. I use load steps to change boundary types. After the first load step has been finished, the simulation stopped. An error message says: Length scale at the inlet boundary was zero. But I think the length scale was difined when writing the geometry file, in my case I used 0.001 for mm. And I am sure I never changed the length scale in the subroutines. Any one has an idea? Thanks.

It is the turbulent length scale.

But the turbulent length at the inlet boundary is 0.0036 in my model. what's wrong?
