Welding simulation with FAST3D method in Visual Weld

A new method is described, which allows to reduce computation time significantly. It is used for transient simulations with moving heat source, mainly for long welds. Its advantage is that it does not require any additional manipulations with the model.

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.

Modelling pretension of Bolts

To simulate bolt pretension, a new medium called PRELOAD has been developed. With this medium, the strain generating the pretension is automatically computed and applied on the model.

3D Combine

As existing 2D Combine in Visual-Mesh, 3D Combine has been introduced to undone refinements.
