Analytical fields: with eulerian_field_source: analytical, the field is the case's properties.initial_conditions.source, re-evaluated each step it depends on t; an optional pressure sets P. operation_mode.analytical_type and uniform_flow are refused, naming the replacement. The domain is the case's grid: TGV3D no longer assigned its own. config/solvers/Analytical-Zero.yml, Analytical-UniformFlow.yml and Analytical-TGV3D.yml are one Analytical.yml. FaceFlux interpolation works with every analytical field, and a study sweeps a uniform stream through case.properties.initial_conditions.source.constants.U.
Fixed: an expression beginning with - and a letter stopped the run, on an inlet, an initial condition or a particle field, because PETSc read it as a second option. Taylor-Green boundary values on the x and y faces evaluated sin(k*x) with a loop index in place of the wavenumber.
