Icon nesting error

Hello @TJDOFLEARN ,

there are several approaches you could take in your specific case.

  • Given that you’re certain that your grids match and you’re just dealing with a precision issue, you could comment out the relevant grid consistency checks on lines 176 - 237 of subroutine m3_ck_ctmmet.F and then recompile ICON

  • you could presumably also edit line 277 in the same file linked above to change 94000 FORMAT( E15.5 ) to 94000 FORMAT( E15.4 ) or 94000 FORMAT( E15.3 ) to require a lower level of precision matching but leave the actual consistency checks in place and then recompile ICON

  • for a more robust and general solution, the code in lines 176 - 237 could be updated along the lines described by @cjcoats in this related post.
