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.

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.

Using "startx" for Remote Display

In most compute environments today, users have a personal desktop (running the Windows operating system) and have access to a remote cluster to perform their simulations.  The remote cluster usually consists of a few to hundreds of powerful machines that are used by many different users.

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.
