Horse saddle distortion modelling in Visual Weld

Welding of structures involves complex interactions between thermal, metallurgical and mechanical phenomena leading to residual stresses and distortions, which play a major role during subsequent service of these structures. Controlling material characteristics, residual stress and keep distortion within tolerances via the computer can significantly enhance the performance, the quality of the product and the structure’s service life

Overview of CSM Welding Advisor in Visual Environment 18.0.2

This tip is to give an overview of new CSM welding advisor in Visual Environment 18.0.2. This new advisor comes in replacement of Visual Welding advisor and uses Assembly solver to perform transient welding simulation.

CFD-VIEW Colormap Options: Static, Dynamic, and Cumulative

The Colormap Settings panel in CFD-VIEW assigns colors to data sets. Identical data values on an object are displayed with the same color if they are using the same colormap display. Three options offer the user the opportunity to select the mode for updating the colormap as the underlying data changes, for example during transient simulations. These options are: Static, Dynamic, and Cumulative

Using Region sources in CFD-VisCART

In order to control grid spacing at user-defined locations, mesh sources are a common tool in CFD-VisCART (Figure 1). Point, Line, Curve, Plane, Box and Surface sources have been available for several years. Cylinder and Sphere sources were introduced a few years back. To extend this tool set further, CFD-VisCART V2013.0 introduced Region sources.

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.

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.

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.

Grouping parts during data import in CFD-VisCART

When dealing with complex industrial models such as cars and airplanes, hundreds of parts need to be managed. Each one of these parts may also be subdivided into different components. In order to easily manipulate these different parts and components in CFD-VisCART, you can make use of the grouping feature.
