Visual-Environment Highlight of Visual-Seat: STAN Thermal Dummy

STAN is a thermal dummy to test thermal comfort and moisture management characteristics of automobile, truck, and airplane seating. This device is commercialized by Thermetrics® and some relevant information can be found here: https://thermetrics.com/products/manikin/stan/. In collaboration with Thermetrics, ESI developed a numerical model of the STAN dummy for the prediction of its thermal behavior. No humidity is managed in this version of the model. A process for the setup of the seating and the thermal simulations of the STAN dummy have been added in this version.

Visual-Environment Highlight of Visual-Seat: Sewing Simulation Guided Setup

Sewing simulations aim at assembling flat cover patterns and wrapping them around deformable foam block. This application exists in Visual-Seat for many versions as a set of toolboxes and functionalities enabling to set-up this type of input. This has been enhanced with a workflow gathering all tools and functionalities and proposing them in the right sequential order to provide some user guidance.

Visual-Environment Highlight of Visual-Seat: Foam Blocks Positioning

When assembling the different components of the seat, it may happen that the foam at rest is intersecting the frame and/or the suspensions. In order to remove those intersections, a simulation-based technique had been implemented previously by applying surface pressure on foam. Upon customer request, a new method has been added where the frame (and suspensions) can be scaled down and moved initially to retrieve progressively their size and position during simulation, when the contact with foam is active.

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
