How to define height of constraint UDT profile with respect to the Blankholder?

Method to constrain the height of UDT profile bulge with respect to the Blankholder

How to define tipping for free double parts with existing forming direction?

Recommendation to position properly the free double parts in case the forming direction is predefined.

How to get back the hidden Part Definition after accepting dialogue?

Option to deactivate to get back the hidden part definition after accepting dialogue.

How to improve the update performance on iterations?

Recommendation to optimize the update performance during iterations.

Internal injection lines modeling

Internal injection lines on a shell model (i.e. made of internal element edges) are not supported by the parallel solver.

Direct Opening of a mesh

The creation of a RTM project and loading of the model mesh is usually done in 2 steps.

Coupling between PAM-FORM and PAM-RTM: multiple part mapping

Coupling between PAM-FORM 2G and PAM-RTM is done through a .DSY file. Thus, pre-forming process is simulated with PAM-FORM 2G and resulting fiber orientations that will affect permeabilities are transferred to PAM-RTM model setup.

How to report and talk about simulation time in an objective manner

Reporting or talking about simulation time is a difficult subject. In the article a way to manage this problem in an objective manner is given.

Materials in the database - Which material properties to use with respect to the three methods to simulate the heat effects of welding

A material is described with exactly one set of material properties. In simulation engineering - depending on the applied method and the moment in time when the simulation is carried out in the product development cycle - only subsets of a full material data set might be required. In this article is outlined which subset is used for which purpose, what is available in the database, and what can be simulated.

The transient method – the third out of three methods to simulate the heat effects of welding

In order to meet different requirements from first design to start of production, three different methods are available in the Virtual Welding & Assembly Suite from ESI. The third one – the transient method – is used when not only distortion but also residual stresses and microstructure need to be evaluated. The part size allows running a heat source gradually. Compare it with a formability evaluation in sheet metal forming. A motorcycle rim may serve as an example.
