On the time step!
 
When I use Fluent to compute 3D flow field, the following information appears: ¡°time step reduced in 2 cells.¡± What does it mean? Then, the computation process stop because of the divergence.I don't know the reason. Do I need to reset any parameters? Thank you!

Re: On the time step!
 
Just reduce your time step,

choose a time step which is less than:

T = L / U

L --> smaller cell dimension

U --> mean velocity of the flow

Hope this could help,

Best regards,

Jkl.
