Tips & Tricks

Here you will find articles on how to solve specific issues related to ESI's software solutions. Missing ESI products will be added progressively. Each article has a short abstract which is accessible to everyone. As logged users you can see the full article with all attached screenshots, and you can post comments related to each article.

Visual-Environment Highlight of Visual-CFD: Multiphase Flow
In fluid mechanics, multiphase flow is the simultaneous flow of materials with two or more thermodynamic phases. These phases may consist of one chemical component (e.g. flow of water and water vapour), or several different chemical components (e.g. flow of oil and...

Visual-Environment Highlight of Visual-CFD: Adjoint Optimisation
The adjoint method has long been considered as the tool of choice for gradient-based optimisation in computational fluid dynamics (CFD). The adjoint method, allows computation of sensitivities, i.e. the derivative of the objective function with respect to the design...

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...

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...

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.

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...
