Hi!
My previous message about new output variable was “XIOS error in the case of determination of new output variable“. I believe that I found reason. I’v used for calculation my additional module with my new field. In this case field calculated normaly, but can’t be visiable by XIOS in module icewri.F90 (despite the fact that the variable was described in a standard module ice.F90). Now I moved the variable calculations to the standard module icestp.F90 and XIOS work normaly.
