io_fesom_file.F90 can not find dimension with size 0

[JanStreffing]

I've been trying to get TCO319-BOLD running for Nils Hutter and GEOMAR.

I am faced with the following error:

1795:  error in line          525 io_fesom_file.F90 can not find dimension with size           0
2177:  error in line          525 io_fesom_file.F90 can not find dimension with size           0
 385:  error in line          525 io_fesom_file.F90 can not find dimension with size           0

The line in question:

fesom2/src/io_fesom_file.F90

Lines 515 to 527 in 2c049ce

	! the dim has not been added yet, see if it is one of our allowed mesh related dims
	if(len == m_nod2d) then
	info = dim_info( idx=this%add_dim('node', len), len=len)
	else if(len == m_elem2d) then
	info = dim_info( idx=this%add_dim('elem', len), len=len)
	else if(len == m_nl-1) then
	info = dim_info( idx=this%add_dim('nz_1', len), len=len)
	else if(len == m_nl) then
	info = dim_info( idx=this%add_dim('nz', len), len=len)
	else
	print *, "error in line ",__LINE__, __FILE__," can not find dimension with size",len
	stop 1
	end if

Anyone got an idea what's causing this?

I found I can activate/deactivate this error by turning on / off dynamic backscatter:

    add_namelist_changes:
        namelist.dyn:
            dynamics_visc:
                opt_visc: 8

Default opt_visc: 7
