Low Mach Preconditioning - Steady Flow Over a 2D Cylinder

Low Mach Preconditioning - Steady Flow Over a 2D Cylinder
Low Mach preconditioning is a way to accelerate convergence towards steady state solution by scaling the disparate eigenvalues of a system to the same order of magnitude for time-marching schemes. The preconditioning matrix applied in FASTRAN is chosen in such a way to... read more

2 - Temperature Thermal Plasma

2 - Temperature Thermal Plasma
For high-pressure thermal plasma sustained by direct current, the temperatures of electrons and gases may differ from each other. A 2-temperature approach better accounts for the overall phenomena than the 1-temperature model, in which the thermal equilibrium of... read more

Simulation of a Spinning Fan using User Defined Subroutines

Simulation of a Spinning Fan using User Defined Subroutines
This example shows flow results obtained for a fan spinning at 3485 RPM. The following approach was taken to simulate the fan. A ugrid user subroutine is used to rotate the fan and shroud grid as a solid body. The parametric inputs, time step size and the user... read more

Generating Multi-Domain Mesh in CFD-VisCART

Generating Multi-Domain Mesh in CFD-VisCART
The Multi Domain mesher generates a multi-zone volume mesh that captures the geometric shape of the model. This mesher is typically used for applications where more than one zone or region needs to be meshed (e.g., problems with fluid and solid regions). read more

Generating Projected Single Domain Mesh in CFD-VisCART

Generating Projected Single Domain Mesh in CFD-VisCART
The Projected Single Domain mesher generates a single-zone volume mesh that captures the geometric shape of the model. As only one zone or region can be meshed, this mesher is typically used for applications where either only the fluid region or only the solid region... read more

Generating Stair-step/Cartesian Mesh in CFD-VisCART

Generating Stair-step/Cartesian Mesh in CFD-VisCART
A fully Cartesian or Stair-Step volume mesh does not capture the geometry curvatures and thus results in a jagged (stair-step like) rendering of the geometry surfaces. This type of mesh has some advantages and can be used in different ways ... read more
