Every project starts with a practical problem from our industrial customer. An example is the problem to control glass production in such a way that the end products like bottles have the correct shape.
Production of bottles consists of two steps. In the first step liquid glass is pressed or blowed to a preform. The second step consists in further blowing this preform to the desired final form. Both steps are modelled as creeping flow, because glass is very viscous. This modelling is achieved in the form of the so-called Stokes equations. Heat transfer, which at low temperatures occurs in the form of radiation, is also important for the final form of the bottle. Therefore radiation models like the Rosseland model are being used.
In order to obtain practical solutions to this very complex production process, efficient computational tools are employed to simulate glass flows. Existing software may not be directly suitable, obsolete or too slow. Dedicated algorithms are need in order to obtain accurate, numerical solutions to the complicated models. If desired, LIME delivers an interface for the algorithms or implements them in the environment of the customer.
