Always Make Sure You Have a Good Mesh Quality

The mesh has a great influence on the solver convergence and solution of every CFD Simulation. The user is strongly advised to check the quality of a numerical mesh.

CFD-ACE+ V2011.0 Physics Compatibility Matrix

Have you ever wondered what would happen if you turned on all of the physics and features of the CFD-ACE+ solver? Or if it is even possible? More likely, you have run into a new modeling task that requires you to use modules and features together that you have never used in those combinations before, and would thus like to know if they are compatible with each other.

DTF utility: the -vd and -ud options

The DTF utility offers several options for viewing and manipulating simulation data in a DTF file. Simulation data is essentially all settings that are not Volume Conditions or Boundary Conditions. By using a couple of DTF commands, you can update the data in the DTF file without opening it in CFD-ACE-GUI. In this tip, we will demonstrate how to use the -vd and -ud options of the DTF utility.

Optimization using an Adjoint Method with PAM-FLOW

The CFD optimization of different car components has the potential of significantly shortening the design process (Othmer & Grahs, 2005).  The adjoint method recently implemented in PAM-FLOWTM is an advanced approach which aims to compute the sensitivities of the cost function and to plug them into a gradient-based optimization algorithm.

Copy/Paste Viewpoint tools

Usually, when performing a particular simulation, it is necessary to compare the results of similar models or the same model at different operating conditions. It is important that the two (or more) cases being compared be viewed from the same angle and at the same zoom level.
