Pre-compiled Code

**If you have already copied the precompiled code for ideal cases to your working directory, then you may skip this part and move down to the "set up the case of your choice section."

The pre-compiled code is available from: /kumquat/wrfhelp/PRE_COMPILED/WRFV3_IDEAL_bin.TAR.gz Copy the tar file to your working directory and untar. This will generate a directory called 'WRFV3_IDEAL_bin', and inside that, you will see the following two directories: WRFV3_IDEAL WRFV3_IDEAL_3D The code is compiled with: (WRFV3_IDEAL): x86_64 Linux, gfortran compiler with gcc (serial); option 32 on these machines (WRFV3_IDEAL_DM): x86_64 Linux, gfortran compiler with gcc (dmpar); option 34 on these machines

Source Code

The source code is available from: /kumquat/wrfhelp/SOURCE_CODE/WRFV3.7.1.TAR.gz Copy the tar file to your working directory and untar. This will generate the following directory: WRFV3 Within that directory, you will need to: ./configure ./compile em_case_of_your_choice **Note: If you are compiling a 2D case, you must compile the code serially; otherwise you can compile in parallel (dmpar) mode. Recommended options to compile the code are: (serial option): x86_64 Linux, gfortran compiler with gcc (serial); option 32 on these machines (parallel option): x86_64 Linux, gfortran compiler with gcc (dmpar); option 34 on these machines

 

Set up the case of your choice

cd WRFV3_IDEAL/test/em_case_you_desire


• Edit the namelist.input file
• Change length of integration, frequency of output, size of domain, time step, physics options, and other parameters
• Some basic descriptions of the namelist variables are available from the OnLine Tutorial page
• More detailed information is available in Chapter 5 of your ARW User's Guide
   
• If you see a script in the test case directory, called run_me_first.csh (this links some data files that you might need to run the case), run it first by typing:
  
        ./run_me_first.csh
   
• Run the initialization program (This will generate a wrfinput_d01 file in the same directory. Idealized cases do not require lateral boundary files because of the boundary condition choices they use, such as the periodic boundary condition option):
   
       ./ideal.exe
   

Run the model

 
./wrf.exe >& wrf.out
 

Generate graphics for your case

Pick a graphical package and generate plots.
ARWpost, NCL and RIP4 can plot idealized model output.

 

If this was successful, you can continue to run another case of your choice.
