Why there is no nest*.ww3 after running ww3.shell?

[abayhaqi]

Hi All,
I am new to WW3. I have run a model. I set the output request of Type 1 (field mean wave parameters) and Type 5 (nesting data) in ww3.shel (please see the attachments). However, why the output file of nest*.ww3 does not appear after the ww3.shel running is finished?

Did you also define your nest(s) in ww3_grid.inp? (see here)
