How to create a complex blank holder with PAM-DIEMAKER for CATIA V5

This video shows how the complex blank holder of a double action draw die can be created from multiple segments using a combination of standard CATIA and special PAM-DIEMAKER for CATIA V5 functions all available inside the Blank Holder dialog.

Improve trimming with Overshoot

Trimming in PAM-STAMP can fail due to a too short trimming segment curve leading to not cut properly the blank mesh. This can be solved by using Overshoot option in PAM-DIEMAKER for CATIA V5.

Process optimization: the future of numerical simulation software

Optimization is becoming a very popular word. However, what does it mean and what does it involve? The goal of this e-tip is to give some keys about optimization concepts and its use in process optimization. In a first stage, we will describe the type of optimization problems that could be solved and in a second stage, the principles and algorithms will be presented. Finally, advantages and drawbacks of the different methods and algorithms will be addressed, with respect to the different types of optimization problems which can be solved.

Casting simulation: from prototype to performance

Passenger safety in cars, planes and other transportation vehicles is an ethical obligation, a legal issue and a technological challenge. Simulation is a well implemented tool in order to test the behaviour of a car body during crash. The models, including rapid deformation and rupture, are sophisticated and reliable. Currently, most properties used in such simulations correspond to homogenous and defect free materials. However, cars are manufactured before being crashed. And manufacturing routes such as casting, but also stamping, forging or welding, do not provide defect free and homogeneous materials.

Parallel processing

“To pull a bigger wagon, it is easier to add more horses than to grow a gigantic horse.” This paraphrased quotation nicely expresses the basic concept of parallel processing. The speed of sequential computers has been doubling every eighteen months, according to Moore’s law. However, at any given time, that speed is limited by the state of the art in integrated circuit design and manufacturing. To circumvent that limitation, it is possible to split a given computationally intensive task among multiple processors working simultaneously.
