Hi all,

For my internship I'm doing research on a specific wind over the Caspian Sea. As this area has sea ice in the northern part of the Caspian Sea I also wanted to do some runs with Polar WRF. To start, the normal engine WRF 4.1.2 has no problems at all in any of the runs. However, with the Polar WRF engine (which seems to be compiled well_) there are some problems with the executing of real.exe, and we do not understand what could be the problem. UNGBRIB.exe and METGRIB.exe do not encounter problems.

I am encountering the following problem in real.exxe:

Max map factor in domain 1 = 0.98. Scale the dt in the model accordingly.

In the attachment the rsl.error.0000 and rsl.out.0000, the namelist.input and namelist.wps and an met_em file of the first timestep can be found. If more is necessary, please let me know. I hope you can help me out. Many thanks in advance!

I guess polar WRF has some unique features different to standard WRF. Unfortunately we don't provide support for polar WRF due to very limited human power here in NCAR. I am really sorry.
