This is a step-by-step guided introductory tutorial for 3-D geometry creation and structured grid generation in CFD-GEOM.

This tutorial is designed to simulate the “real-world” working process capabilities of CFD-GEOM. An IGES file generated from a CAD package is read into GEOM. Then, the surfaces are trimmed, an unstructured domain is created, and the combustor model is gridded.

The steady state conductive heat transfer to the air-gap between infinitely long concentric thick-walled cylinders is modeled and compared with an analytical solution. This is a step-by-step guided introductory tutorial for setting up a heat transfer model in CFD-ACE+.

Lorentz force is the force exerted on a charged particle in an electromagnetic field. Lorentz forces can be used to control flow separation. In the example of flow separation over a cylinder, the application of Lorentz force in a direction tangential to the surface of the cylinder results in moving the separation point rearward on the cylinder surface. This causes a reduction in the drag over the cylinder.

In typical electro-magnetic problems, the electric field and the magnetic field are coupled with each other. In accordance with Ampere’s Law, a varying current or voltage induces a varying magnetic field, which in turn changes the electric field itself.

This tutorial describes the steps for creating new surfaces to close tee open-ends of a geometry.

This tutorial describes the steps for creating new surfaces between two features, or two outlines, or an outline and feature.

This tutorial describes the steps for creating new surfaces by the selected points.

This tutorial highlights the fundamental steps for handling critical feature preservations.

In this tutorial, the geometry of a bent pipe is optimized. The bent section of the pipe must provide 90-degree change of direction for a fluid flowing through it. The objective is to determine the bend radius “R” that provides the minimal (optimal) pressure drop through the pipe.

Dielectrophoresis occurs because of the interaction between the induced dipole and the electric field. The interaction creates a net force, which depends on both the gradient of the electric field and electrical properties (permittivity and conductivity) of the particle and the media. The net force applies on partices, charged or not, and drives them to move. This technique can be used in the analysis, manipulation, and separation of cellular scale and nanometer scale particles like cells, DNA etc.

DNA Hybridization is a method for combining one strand of DNA sample against other (second) strand of DNA probe on a single support membrane. The degree of binding depends on the molecular geometries. The signal for a given geometry and kinetic parameters are evaluated in this tutorial.
