Hi,
I want to use vertical nesting in the smallest domain of a 3 domain setup.
I am experiencing this error: ERROR: the last specified eta_level is not 0.0
I am quite confused by it as the level is set in the namelist. I have pasted a part of the namelist. What mistake am I doing?

vert_refine_method = 0,0,2,
e_vert = 35,35,45,
dx = 27000, 9000,3000,
dy = 27000, 9000,3000,
eta_levels(1:35) = 1.000, 0.993, 0.983, 0.97, 0.954, 0.934, 0.909, 0.88, 0.8406663, 0.8013327,
0.761999, 0.7226653, 0.6525755, 0.5877361, 0.5278192, 0.472514,

Please try
eta_levels(36:80)= 1.0000, 0.9946, 0.9875, 0.9789, 0.9685, 0.9562, 0.9413, 0.9238, 0.9037, 0.8813, 0.8514,

I run your case. Below should be the settings that work:

Thank you, it's working now.
 
One thing I would like to mention is that RRTMG scheme does not seem to work with vertical nesting as mentioned in README.namelist, only RRTM works.

What is the error when you run RRTMG with vertical nesting?

I don't have the error log with me but the model had crashed at the start stating that vertical nesting only worked with RRTM scheme.
