Stab uses a direct approach with either Chebyshev collocation or high-order
finite difference. This is complemented by the shoot solver which uses
an ODE solver with Conte orthogonalization and shooting to satisfy the boundary
conditions. I suggest using shoot to polish the eigensolutions identified
by stab.
The stab code has been updated to build with the GCC gfortran compiler on
both MacOS and Linux and older builds (SGI, Cray, IBM) have not been recently
used so makefiles for those will need updates.
To build use:
ln -s gcc.mak Makefile
make USE_NR=1stab currently uses a couple of Numerical-Recipes in FORTRAN
routines that are commercially licensed and therefore not distributed here.
You can easily replace these with public versions and are encouraged to do so.
- It would be easy to remove the dependency on NR and I encourage someone to do so.
- You may not add the NR software to this repository and you may only use it if you have a valid license to do so.
- I have not recently tested the finite-Reynolds number surface roughness solver so please use with caution.
