Error message: "Write interval too large" when my time step is 1 second

For incompressible steady state CFD. Please help

@NuclearPotato, this is not related to the time step length, but rather the data from the time steps that you are saving

Please see write control in the documentation:

If you are doing a steady-state analysis, make sure that the end time value and the write control interval are the same.


why is it required to have same value of both can’t write interval can be less.

It is not a must Artitra - but then you will generate more data which means the final size of the file you are working with is bigger, does that make sense? So you are basically just changing the frequency of output.
