Relation between Bulk Modulus K, Shear Modulus G, Young's Modulus E and Poisson's ratio ν

This tip explains the relations between the parameters that describe the linear elastic behavior of materials

How to convert force-deflection into true stress-strain curves?

This tip helps to convert typical tensile test data into stress-strain curves to be used in many material models of Virtual Performance Solution (VPS)

Fiber volume content contour

Two dedicated composites contours are available in PAM-FORM 2G post-processing: Shear angle and fiber directions.

Coupling between PAM-FORM and PAM-RTM: multiple part mapping

Coupling between PAM-FORM 2G and PAM-RTM is done through a .DSY file. Thus, pre-forming process is simulated with PAM-FORM 2G and resulting fiber orientations that will affect permeabilities are transferred to PAM-RTM model setup.

Grouping option for CFD-VIEW Data Import

Grouping feature in CFD-ACE+ GUI and CFD-VIEW comes in handy when working with complex industrial models. This feature allows putting BC patches or VC entities into a group that can be manipulated easily, to either set up properties or display specific post-processing attributes.

CFD-VIEW Scripting is easier than ever with Journaling

In addition to the numerous options and tools available via the CFD-VIEW user interface, the scripting capability of CFD-VIEW allows you to perform complex data processing on your simulation results, and gives you the option to run the post-processing phase of your simulation in batch mode.

CFD-VIEW: Working with cell-center data in batch mode

Many improvements have been made in CFD-VIEW that allows the manipulation of cell-center data. The latest cell-center data additions implemented in CFD-VIEW V2011.0 include, for example, support for the MinMax Probe and the Calculator.

"Per Pixel Lighting" display option in CFD-VIEW

When visualizing CFD solutions, it is often of interest to see a particular range of variable values, and it is therefore useful to be able to clip the surface coloring to that range, as to obtain a clearer view of the areas affected by the variable.

Visualizing decomposed model without zonal interface outlines

Running a simulation in parallel allows quicker turn around for larger and complex problems. Such parallel jobs require the computational domain to be decomposed into multiple zones. Such a multiple-zone file may be inconvenient to post-process in CFD-VIEW because zonal interface outlines will be visible and the original surfaces would have been split. As depicted in figure 1 below, these outlines can be numerous and may therefore hinder the clarity of the model.

Visualizing particle size effect on Spray particle trajectory

When analyzing flow vectors, one can get a general trend of the direction of the flow and locations of recirculation. But what if you need to specifically know where a particle will end up? Maybe release points need to be studied. Then, the size and mass can make a difference in the path a particle travels.
