Flowchart for model construction, FEM meshing and numerical computation of fluid pressure and velocity fields in geometric conduits. Geometric models are constructed in Computer Aided Design (CAD) package and meshed using unstructured finite elements. Meshed samples are input into CSMP++ where SuperGroup objects representing aggregates of physical entities in the geometric models are formed. Material properties and initial conditions are then assigned with Interrelations subclass being used in computing variable coefficients. Integral forms of the Partial Differential Equations (PDEs) arising from the FEM are assembled term-by-term using numerical PDE operator classes (e.g., NumIntegral dNT op dN dV). Computed fluid pressure and Stokes velocity are displayed and output to VTK for visualisation.
