Find dominant path in SEA models

Statistical energy analysis (SEA) computes the flow of vibrational energy between coupled subsystems by applying principle of conservation of energy. Using conservation of energy power balance equations which govern response of a system. Since it is based on energy flow, path analysis is straight forward. In this article it is described how to extract the dominant path in a complex model using SEA and VA One . As a result the subsystems in the dominant path are displayed in the 3d window (All other subsystems are hidden).

Using a template CDL file for quick case set up in CFD-CADalyzer

If your simulations with CFD-CADalyzer typically include the same or similar type of physics, materials and boundary conditions then you can make the case setup process very efficient and quick with the use of a template file - a CDL file that includes the typical simulation settings.

Inverting Models in CFD-CADalyzer

Computational Fluid Dynamics (CFD) requires the discretization of a geometry bounded by it's wetted surfaces. In CAD, the solid parts are created without the corresponding fluid volumes, i.e. negative space.

Blanking, Grouping and Selecting Entities in CFD-CADalyzer

When working with models in CFD-CADalyzer, especially the more complicated ones, Blanking, Grouping and Selection tools can considerably simplify model setup and visualization.

Automatic Report Generator in CFD-CADalyzer

The Report Generator in CFD-CADalyzer allows a user to generate and print a detailed report of the CFD simulation that has been set up and run. The user can also customize the report to make it fit his/her needs and demands.
