Hi everyone,

I've met an error when doing the nesting. If I change the output frequency of the history files in croco.in and croco.in.1 to 1 or any positive number, the model will show the following errors:

But when I change the output frequency of the history file to 0, the pattern works fine. Besides, if I don't do the nesting, the model also works fine.

Can anybody help me with this please? Thanks a lot in advance!

That's a new one to me.

Fist decrease your time step to see if the simulation is ok. What is your current time step, pixel size, and cu_max value?

Time steps for the original model, nesting #1 and nesting #2 are 180s, 60s and 20s, respectively. Pixel sizes for the original model, nesting #1 and nesting #2 are 1/12, 1/36 and 1/72 degrees. Cu_max values for the original model, nesting #1 and nesting #2 are 0.1227, 0.1034 and 0.1026.
