How to Obtain Best Results within Reasonable Time from a Heat Treatment Simulation

Heat treated parts are in most cases not clamped during heat treatment, for an FEM analysis, at least a static determined clamping is needed that does not allow any rigid body motion.

Stamping/HT Chaining of 3D Ring - Restart tool in Visual Heat Treatment

This article is to show effects of heat treatment on stresses when industrial mechanical parts are stamped (or welded) by 3 typical heat treatment steps: Heating, Quenching and Tempering. Tempering is generally considered effective in relieving stresses induced by quenching in addition to lowering hardness to within a specified range, or meeting certain mechanical property requirements.

Heat Power display in Visual Weld

The aim of this development in Visual Weld 14.5 + Sysweld 2019.0 is to display the Power Density. Currently, this functionality is only available in the old SysWeld GUI. The new functionality "Heat Power Display" is available through the "Welding Utilities" menu of Visual Weld.

Conversion Files .fdb in .erfh5 on Network Drive

It is not straightforward to do the conversion Files .fdb in .erfh5 on Network Drive in Visual Viewer. In order to make it work properly, it is necessary to map network drive to the local machine. In this way, the files on network could be handled like on local machine and the conversion from fdb to erf will be working properly.

Crash when launching Visual on CentOS

On Linux, at moment of launching Visual-Environmnet, crash happens after having selected Visual Weld. It is possible to try following steps to solve the problem. - Launching Visual in debug mode - Downgrade GlibC to 2.12 - Install freshly NTP

Auto Empty Folders option in CFD-GEOM

When importing large models into CFD-GEOM, you may notice that certain entities listed in the Model Manager may have a red box around them.

Adding Baffles to an Unstructured domain in CFD-GEOM

While meshing the geometries of industrial significance like mixing tanks, reactor and heat exchangers, we may encounter baffles which have negligible thickness but significant area to impact the physics of the problem in terms of momentum and heat transfer. These surfaces may be free-standing or connected to other surfaces from the domain.

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.
