Parametric Studies Using SimManager

Parametric studies are an important aspect of CFD analysis. Parametric studies are used to perform trend base analyses, optimize the deign of a device, and/or to study the affect of different parameters on a process (What if? type analysis).

How to Compare the Model Setup Between Two DTF Files

Have you ever wanted to find the differences between two DTF files? If you have, then you will probably be interested in a DTF utility included in your ESI Software installation. The utility is called dtf_diff and can be found in your UTILS_2009.0/bin directory.

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.
