WRFV4.0 input conversion error

[jmccurr]

Hi, when running wrf.exe with real BC's I've been experiencing an input conversion error (see below) immediately after WRF verifies that the boundary conditions file is acceptable to use. I've checked that the namelist.input options for wrf.exe match those used with real.exe to create the BC files, and all files were created with the same compiler setup (intel 2013). I've attached my wrf namelist, rsl.error output with max debug, as well as the wrfbdy_d01 file used here. Any help would be appreciated.

Hi,
I'm not sure what that exact error is, as it's vague and given by the compiler - not the model. But I do have an idea about one thing that could be causing the problem. Your domain is 377x377, which isn't huge, but isn't small. 1 processor isn't going to be enough to run this. Take a look at this FAQ that discusses determining a reasonable number of processors:

On a side note, I would recommend turning debug_level back to 0. In recent versions we have removed this parameter from the default namelist, as it was initially put in for developmental testing purposes and is rarely useful in helping to troubleshoot. If anything, it just adds a lot of junk to the rsl* files, making them nearly impossible to read, and can sometimes even cause the rsl* files to be so large that disk space issues occur.
