Process optimization: the future of numerical simulation software

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... read more

Casting simulation: from prototype to performance

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... read more

Parallel processing

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’... read more

The manufacturing of sand cores

The manufacturing of sand cores
The manufacturing of iron, steel and non-ferrous castings is achieved using a variety of casting process designs, and most of these involve the use of sand cores which form the internal shape of the casting. A good quality casting requires a good quality core.... read more

Modeling the solidification of cast irons

Modeling the solidification of cast irons
Successfully modeling solidification of Cast Iron is of great help for the foundries to reduce their production costs and thus to increase their profits. If the basic physical solidification phenomena are correctly modeled by the simulation tools mold risering can... read more
