Fluid

Finite Element fluid flow solver.

Physical equation:

  • Navier-Stokes and continuity equation


Numerical method:

  • Finite Element Method (FEM)

Supported elements:

  • 0D - point - source boundaries
  • 1D - line - source boundaries
  • 2D - triangle - wall boundaries
  • 3D - tetrahedron - fluid domain

Boundary conditions:

  • Inflow - velocity
  • Inflow - volumetric flow
  • Fixed pressure
  • Otflow - free pressure
  • Temperature
  • Heat flux
  • Particle concentration
  • Particle concentration flux

Results:

  • Pressure - scalar
  • Velocity - vector
  • Acceleration - vector
  • Temperature - scalar
  • Heat flux - vector
  • Heat transfer coefficient
  • Particle concentration - scalar

Special features:

  • Heat-transfer model
  • Contaminant dispersion model
  • Fluid can be linked with Heat and use computed temperatures as a temperature boundary condition on the walls.
