1) A new guided option is available to output forcing file that can be reused for a newt nudged cglobal or LAM configuration. It is activated using guided_type flag :
guided_type = nudging_forcing

in this case, new run.def parameters are available to control output frequency and output area :
nudging_freq : output frequency in second
nudging_lon_start : longitude starting zone in degree (default=-180)
nudging_lon_end   : longitude end zone in degree (default=180)
nudging_lon_delta : longitude resolution ind degree (default=1.)
nudging_lat_start : latitude starting zone in degree (default=-180)
nudging_lat_end   : latitude end zone in degree (default=180)
nudging_lat_delta : latitude starting zone in degree (default=-180)

2) improve nudging, and merge nudging functionality when using forcing file coming from previous dynamico simulation or ERA5 reanalysis
