there is one small issue related to the number of longitudes, which is because of the Helmholtz solver or something: you need to define nlon so that it is 2**k* 3**m * 5**n + 2*(npbdpts+1) . (k,m,n are any integers). Thus, e.g. 126 (2**3 *3 * 5) and 134 (2**7+6) fulfill this condition, but your 130 does not. If you want a resolution of 0.1 deg (11 km), you need to tune the east/west accordingly,.
Laura and others,
just to clarify that with the recent HIRLAM versions the requirement of nlon being that of 2**k* 3**m * 5**n + 2*(npbdpts+1) is no longer there IF one choose in scripts/Env_expdesc the value of LHHITER as yes, (use of iterative Helmholtz solver as met.no had been applying for many years). I mentioned this in earlier post

I'll be back to address Felix's question about LBC in a later post.
