Tips & Tricks

Post-Processing Using Iso-Surfaces

In many cases, user simulates a multiphase flow inside a duct. It is sometimes useful to create a nice model in CFD-VIEW which can clearly present the flow inside the duct. The following example is based on Tesla Valve geometry, which is being filled by a liquid in transient mode.

Conditional Expressions in CFD-VIEW Calculator

Conditional expressions can be used in the CFD-VIEW calculator to put logic into the calculator expressions. For example you could create new variables that have a specified range of values. These variables can then be used to make plots and perform calculations.

Calculating Mass Flux in CFD-VIEW

Flow analyses often require information about mass flux computed across a surface in the computational domain. If the surface of interest happens to be a boundary condition (inlet or outlet) or a fluid-fluid interface, the mass flux across it can be found in the output (modelname.out) file if the “Mass Flux Summary” option is turned on under the Out/Print tab in CFD-ACE-GUI.

Particle Tracing in CFD-VIEW

A Particle Trace or Streamline is the trajectory of a particle moving in a fluid. Being able to visualize/analyze this trajectory can be very helpful in understanding flow patterns and flow distribution.

Making Plots Along Constant Radius Curves

How do I plot a variable along the circumference of a circle or circular arc? The above query has been made several times by CFD-ACE+ users. In case of cylindrical geometry, it’s very useful to have a plot of the desired variable along a circle of certain radius.

Creating Strip Charts in CFD-VIEW

The Strip Chart feature in CFD-VIEW is a very useful tool for analyzing time dependent quantities from transient simulations. The feature can be found in the second row of the Operator Palette as shown. This note provides you with an overview of how to use and implement the Strip Chart feature.

File Based Animation with CFD-VIEW

The animation panel in CFD-VIEW can be used for file-based animations, where time dependent data files are loaded one by one to show the temporal aspects of the simulation.
