10(A)  Directions for running a test case
11
12A suite of tests for the WRF model ARW (Advanced Research WRF) core
13can be found in the directory "test".  Each subdirectory in /test
14contains the necessary data (except for the real data case) and
15input files to run the test specific to that directory. 
16To run specific test, builld the WRF model
17and the necessary initialization routine by typing
18
19-> compile "test_name"
20
21in the top directory (the directory containing this README file).
22For example, to build the executables for the 2D (x,z) squall line
23example for Eulerian mass coordinate model, you would type the command
24"compile em_squall2d_x".
25
26after a successful build, go the the specific test directory:
27
28-> cd test/"test_name"
29
30run the initialization code
31
32-> ideal.exe
33
34and then run the simulation
35
36-> wrf.exe

40(B) Available Test Cases
41
42The available test cases are
43
441) squall2d_x (test/em_squall2d_x)
45
46   2D squall line (x,z) using Kessler microphysics
47   and a fixed 300 m^2/s viscosity.  periodicity
48   condition used in y so that 3D model produces
49   2D simulation.  v velocity  should be zero and there
50   should be no variation in y in the results.
51
522) squall2d_y (test/em_squall2d_y)
53
54   Same as squall2d_x, except with (x) rotated to (y).
55   u velocity  should be zero and there
56   should be no variation in x in the results.
57
583) 3D quarter-circle shear supercell simulation
59   (test/em_quarter_ss).
60
61   Left and right moving supercells are produced.
62   See the README.quarter_ss file in the test directory
63   for more information.
64
654) 2D flow over a bell-shaped hill (x,z) (test/em_hill2d_x)
66
67   10 km half-width, 2 km grid-length, 100 m high hill,
68   10 m/s flow, N=0.01/s, 30 km high domain, 80 levels,
69   open radiative boundaries, absorbing upper boundary.
70   Case is in linear hydrostatic regime, so vertical tilted
71   waves with ~6km vertical wavelength.
72
735) 3D baroclinic waves (test/em_b_wave)
74
75   Baroclinically unstable jet u(y,z) on an
76   f-plane.  Symmetric north and south, periodic east and west
77   boundaries.  100 km grid size 16 km top with 4 km damping layer.
78   41x81 points in (x,y), 64 layers.
79
806) 2D gravity current (test/em_grav2d_x)
81
82   Test case is described in Straka et al,
83   INT J NUMER METH FL 17 (1): 1-22 JUL 15 1993.
84   See the README.grav2d_x file in the test directory.
