DTF Commands: The -ud and -vd Options

The DTF utility offers several options for viewing and manipulating simulation data in a DTF file. Simulation data is essentially all settings which 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 the it in CFD-ACE-GUI. In this tip, I will demonstrate how to use the -vd and -ud options of the DTF utility.

Working with Multiple Simulations in a DTF File

One feature of the DTF file format is that multiple simulations can be stored in a single DTF file. In most cases, you will be working with multiple simulations when you are running parallel computations. This is due to the fact that you must decompose the original mesh to obtain the decomposed mesh.

2004 User Group Meeting

The 2004 User Group Meeting is only 2 months away!  This year’s meeting will be held in Detroit on November 3-4 in conjunction with the ESI-Group AmeriPAM event. The focus of the CFD portion of this event is learning and productivity enhancement.  We have found that our weekly tips/tricks emails have been quite well accepted and the feedback indicates that you want more of this type of information.

V2006 CFD-ACE+ 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.

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.
