LWPC v.2.1

SPAWAR LWPC Longwave Propagation Code v.2.1 was described, validated, and used by numerous authors. Here we present a Python interface to the original Fortran code.

Minimum edits to source to compile on modern (non-Watcom) Fortran compilers such as Gfortan.

Build

cmake -B build
cmake --build build

Run

./lwpc

the file output/lwpm.lwf is created with the simulation output, the console says "Normal run complete" and stderr is 0.

Examples

Several example inputs are provided:

./lwpc ../gcpath

./lwpc ../lwpm

./lwpc ../jammer

./lwpc ../bearings

./lwpc ../lwflds

Read output

./scan

../output lwpc.lwf

will create text file "scan.log" that will help confirm the simulation was run correctly.
