Dynamics option: eulerian Mass Coordinate Killed error

[prandamulya90]

Hello, everyone.

I am new to WRF model. Currently, I am playing with the data from GFS-NCEP for 2018-04-09 to forecast solar radiation.
First, I run successfully the ungrib.exe and metgrid.exe.
However, when I run real.exe, I could not produce wrfinput and wrfbdy. The terminal showed below


Ntasks in X 1 , ntasks in Y 1
REAL_EM V4.0 PREPROCESSOR

DYNAMICS OPTION: Eulerian Mass Coordinate

I tried to look for the error in the various forum but still could not the solution.
Appreciate in advance! Thanks!

Hi,
The reason your real.exe run is likely failing is because your domain is pretty large (622x810), and you are only using a single processor to run real.exe. You will need to make sure you compile WRF for parallel processing (e.g., dmpar - distributed memory), and will need to use multiple processors to run the real and wrf executables. You typically do not need many processors to run real.exe, but take a look at this FAQ for information on choosing an appropriate number of processors for running wrf.exe. You can choose the same amount or fewer for running real.exe.
