Utilities

• Almost all modifications can/should be made via a utility, rather than altering the core code in the program/ directory.
• Utilities are kept in utils/.

Building

To build, in Makefile, set UTIL = utilname (omitting the .f90 extension), then type

> make
> make install
> make util

The last command creates utilname.out.

It is good practice to do a 'make install' to generate a main.info file to keep alongside the executable.

Pre/post-processing

• main.info - Record of settings at compiletime
• ic.f90 - Pre/Post-processing template.
• describe_state.f90 - check time/parameters; see also main.info for outputs.
• changeMp.f90 - change i_Mp value in a state file.
• change_Mp_alpha.f90 - make copies of a state, or extract modes, dependent on changes in length or azimuthal symmetry.
• prim2matlab.f90 - convert to matlab/visit-readable netcdf.

Runtime processing

• runtime.f90 - Processing template.
• newton.f90 - Newton-Krylov.

Non-problem-specific codes

• GMRESm.f90, arnoldi.f - Krylov-subspace methods.
• NewtonHook.f90 - Newton-hookstep method.
