2.2.6. Turbulence

The turbulence/ experiment demonstrates how to set up the driving in forced turbulence experiments, where the details of the driving may need to depend on the value of the SOLVER makefile macro.

The hierachical makefile setup (which may be followed by inspecting the config/Makefile and its sinclude statements allows one to override the default choice of the force_mod.f90 or forces_mod.f90 by placing corresponding files in subdirectories under the experiments/turbulence/ directory.

The specific driver in the case where SOLVER=ramses/hydro, for example, resides in experiments/turbulence/ramses/hydro/.

Alternative, as illustrated by the directory experiments/turbulence/stagger2e/, one may place a specialized experiment in a subdirectory, where the TOP makefile macro is correspondingly defined as TOP=../../...
