initialize_fields Subroutine

public subroutine initialize_fields(mesh, fields)

Initializes flow fields and sets simulation initial conditions.

Currently implements a "Start from Rest" condition where all velocities and pressures are zero. IC overrides for restarts or analytical solutions will be implemented here.

Arguments

Type IntentOptional Attributes Name
type(mesh_t), intent(in) :: mesh

The computational mesh.
type(flow_fields_t), intent(inout) :: fields

The fields container to initialize.

      ! Initial condition: Fluids starts from rest. 
      ! Boundary motion and body forces drive the flow from t=0.
