Hermes plasma edge simulation model. Uses BOUT++ framework, adds finite volume operators and neutral gas models.

This is Hermes-1, a cold ion drift-reduced model.

Compiling

To compile, run "make" and specify the location of BOUT++

$ make BOUT_TOP=/path/to/BOUT/

Test cases

• driftwave - Drift wave in slab geometry. To run, execute script "run-driftwave" in this directory

$ ./run-driftwave

Simulations

• linear-device linear device simulation (no neutrals)

• circular Large aspect ratio, circular cross-section. Axisymmetric electric fields and current evolution

• d3d Axisymmetric plasma transport (no electric fields)

• d3d-neutrals Axisymmetric plasma transport with neutral gas

• ISTTOK This test case is for the large aspect ratio circular cross-section device. Grid files are generated by a Python script "circle.py"
