Importing an arbitrary STL surface for post-processing in CFD VIEW

When using the Arbitrary-Cut operator, you have the option to directly import an external surface in STL format into the model. This option, which was first made available in V2013.4, underwent significant performance improvements in V2014.0. This option provides the ability to plot data and process information on any arbitrarily shaped surface. The import process involves reading the STL file and computing the intersections between this surface and the model’s volume cells. Results on the imported surface are interpolated from the intersected volume cells and are independent of the surface mesh size of the STL as long as the surface is properly represented.

 

Updating and Animating a Developing Steady State Simulation in CFD-VIEW

Many users who are running steady-state simulations like to watch the results develop. Most of the time, users hit the "Reload the Same Data File(s)" button again and again. You will be happy to hear that there are two easier ways to do it.

Mirroring Tool in CFD-VIEW

One should always take advantage of geometric and solution symmetry to model just one-half or one-fourth of the computational domain to reduce the computational time by significantly reducing the size of the model. After modeling half or one fourth of the model, you always want to present data for the full model.

Carpet Plots in CFD-VIEW

Carpet Plots are used for visualization of computed data on 2D surfaces. A carpet plot is created by displacing the 2D surface vertically based on one of the variables computed over that surface. The carpet plot can also be colored by the same or different variable.

Using the Clone Feature in CFD-VIEW

As the name suggests, the Clone operator creates an exact copy of the input object. The input object could be a surface (iso-surface, plane cut, geometry surface, border object) or a volume. The drawing style of this copy (or copies) is completely independent from that of the original.

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.
