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.

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.

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.

Boundary layer meshing with CFD-ACE+ [video format]

The accuracy of a CFD solution is strongly dependent on how well the mesh resolves geometry and flow features. This is especially true for near wall regions (boundary layer) where viscous forces are not negligible compared to inertial forces.

How to check what software version you are running

There is a very fast and easy way to verify what software version you are running for your ESI CFD applications. You most likely know that this information is available for the GUI by clicking on 'Help → About ...', and for solvers by looking in the output file.
