+> FIXME: Run in parallel. Still has issue on Wahab.

+### Update 2023-06-02
+
+A few notes:
+
+1. The CFL3D software can only run on Wahab as the hardware was new enough
+   for the instruction sets used in the code.
+   Please do not run this on Turing as it will quit with an error message.
+
+2. With version 6, there is no more need to recompile CFL3D
+   every time you want to run with a different physical system (model).
+   The code now allocates arrays dynamically, so `precfl3d` is not needed anymore.
+
+3. I included the source code in <<#TODO>> directory in case you want to play
+   around and modify the source code.
+
+4. The code was built to NOT read from stdin. Please do not run in this way:
+
+   ```
+   crun.intel ~/CFL3D/bin/cfl3d_seq < MY_INPUT.inp     ### WON'T WORK
+   ```
+
+   Instead, run it in two steps:
+
+   ```
+   cp MY_INPUT.inp cfl3d.inp
+   crun.intel ~/CFL3D/bin/cfl3d_seq
+   ```
+
