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)

Automatic covering of larger unwanted holes in CFD-VisCART

CFD-VisCART meshing automatically closes or covers holes in the geometry that are smaller in size than the cell size specified at the surfaces. To cover LARGER holes, the ‘Max Hole Size to Cover’ feature can be used. This feature, introduced in V2013.2, works to automatically cover larger holes in the geometry during mesh generation, and thus prevents the mesh from leaking into unwanted regions. This feature is available with all mesh types supported in CFD-VisCART.

Internal injection lines modeling

Internal injection lines on a shell model (i.e. made of internal element edges) are not supported by the parallel solver.

Direct Opening of a mesh

The creation of a RTM project and loading of the model mesh is usually done in 2 steps.

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.

Model clipping feature in CFD-VisCART and CFD-GEOM

For better visualization of the geometry and mesh, a model clipping feature was introduced in CFD-VisCART and CFD-GEOM V2013.0. The following sections illustrate the usage and benefits of this feature.

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.

Improve Productivity Using Scripts [Video Format]

As simulations become more integrated with the design process, engineers often spend time on repeated operations that do not contribute to their productivity. There is a need for tools that could capture, preserve and transfer the knowledge within the organization or to its customers.
