THE BENEFITS OF MODULARIZATION: FROM KASKADE TO KARDOS

KARDOS solves nonlinear evolution problems in 1, 2, and 3D. An adaptive multilevel finite element algorithm is used to solve the spatial problems arising from linearly implicit discretization methods in time. Local refinement and coarsening techniques are used to handle the development of the mesh over time.

The software engineering techniques used to implement the modules of the KASKADE toolbox are reviewed and their application to the extended problem class is described. Software techniques for

• dynamic memory management of many small elements,
• dynamic construction of records,
• control parameter handling,
• a notification system,
• generalized solution processes, and
• command line interfaces

At the end of the talk we will summarize our experiences.
