Application reference

Each source file apps/app_*.cc produces an executable with the app_ prefix removed. Debug targets append _debug. Applications read an explicit parameter-file path; when a file supports dimension dispatch, the dimension and space dimension entries select the template instantiation.

MetricFlowX executables are excluded from the build unless both MetricFlowX and deal.II SUNDIALS are available. The two lib1dsolver executables are built from their source files, but their functional code is enabled only when ENABLE_COUPLED_PROBLEMS is on and the library is found with RTTI support. All other executables are part of the normal application target set. The running applications guide explains the parameter-file command format.
