Hi Grenville,
Thank you for looking into this. I can’t think of a reason why this would be causing a problem (aside from compiler issues) as this branch works in Monsoon.
I’m a bit confused regarding the changes you have made. I can find the SUBROUTINE code block in ukca_main1-ukca_main1.F90 and I assume the lines starting with TYPE and USE in your response are additions. Are these additions added directly after the SUBROUTINE block? If you have diff of your changes to the branch I could tell from that.
Many thanks,
James
