<div class="PlainText">About the second comment. I set it just in case because I found in the example. About the OBCS, the indexes can be other than 1,0 or -1. My guess, if you have a big domain and you want to open a boundary in the last row it is easier to
put -1 than 5984. For my experiments, I have designed a circular domain and I decided to leave the two first and last rows and columns as land. I do not think this is causing the problem because if I run the model without forcing period the model works perfectly
fine. He reads only the first time step of my forcing bin file but it works. It is just when I activate the forcing period in the data namelist. </div>

1. please post the SIZE.h file.<br>
unless the behaviors induced by the paramters has changed, the info in thisfile will permit straightening out ofthese extents issues.<br>
<br>
2. below in parm04<br>
delY is set to 43*1 (why set it? i would not assume that there is no side effect from this, maybe there isn/t, i don/t know)<br>

iirc, the values of these arrays are -1,0,1<br>
it/s been a while since i setup and ran a simulation<br>

> Hi, I do think, that this may be your problem, because your fields are actually too small! You use nx=13, when it should be 43. Even if only part of your Northern or Southern boundary is really "open", you need to provide the full field. Please refer to the
documentation for more details. Unfortunately, we don't have any verification experiments with exactly your configuration. Most of the time all boundaries are declared as open, even when only a few are actually "wet", e.g. the verification/dome experiment,
where the open point along the northern bounary are only a few.<br>

might want to hard-wire the paths, as you have done, then you don?t need the rest anymore. Alternatively you could set the environment varialbes NETCDF_ROOT and MPI_INC_DIR, e.g. like this<br>

By the way, do I need the last set of conditions of NETCDF_ROOT and netcdf test? I was thinking to remove them.<br>
