Digital Signal Processing using CFD-VIEW
Signals (stream of data) obtained from physical or numerical experiments often require additional processing to understand/interpret the physics they represent. The processing of signals through digital means is termed Digital Signal Processing (DSP).

Geometric Precision and Filtering in CFD-GEOM
In many cases, CAD models can be dirty and thus do not import well into CFD-GEOM. Repairing these geometries can often take considerable time and effort. Many times, duplicate points, lines, and surfaces are created when importing CAD geometries.

Plotting Multiple Variables in the CFD-VIEW Plotter
Plotting two or more variables on same plot having values of different magnitude/scale becomes difficult or many times impossible. In these cases plotting data with multiple Y-axes becomes very useful and sometimes necessary.

Parametric studies using CFD-GEOM and SimManager
Parametric studies controlled by SimManager give the useful ability to perform several routine simulations. It allows to use CPU time more effectively and reduce user interaction. In other words, it is possible to automate the process of mesh generation in GEOM, model setup in CFD-AGE-GUI, solver run, and visualization in CFD-VIEW. In this user tip, automatic geometry manipulation and mesh creation will be discussed.

Importing external data in the CFD-VIEW Plotter
Comparing computational results to experimental data is a task often asked of CFD analysts and engineers. The line/curve plotter in CFD-VIEW is commonly used for plotting computational results along curves, such as line probes, surface slices, time histories, etc. CFD-VIEW offers a feature that allows users to import experimental or other external data in the same plot, thus making it easy to compare results.

Semi-Structured Domain Stitching in CFD-GEOM
A feature that allows users to stitch together a Semi-Structured domain is available in CFD-GEOM. This feature gives the user flexibility of stitching two end faces with different topologies, i.e. a geometry that cannot be extruded.

User Defined Curve Probes in CFD-VIEW
CFD-VIEW allows the user to create curve probes from a file containing XYZ data. This feature gives the user flexibility of collecting data on any specified/desired curve in the computational domain. As an example of use, these "curved line" probes could be used to sample simulation data at the same locations that experimental data was collected.

Tracking Multiple Variables with Multiple Legends
When post-processing with CFD-VIEW, one may wish to display two different variables on two different objects. This requires the use of two legends to correspond to the different color mapping of the variables. The legend tracking feature in CFD-VIEW can be used to achieve this. If this topic is of interest to you, please read on.

Transparency Feature in CFD-GEOM
In CFD-GEOM, certain entities can now be set to transparent. This option allows you to add transparency effects to your surfaces, faces, and volumes. This can be an excellent way to add shadows/colors and glass effects to the model.

Using the Construction Plane in CFD-GEOM
Point entities in CFD-GEOM are placed in an XYZ (Cartesian) coordinate system. The Construction Plane tool enables you to position a plane in space, and place points on that plane to generate curve entities.
