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,
