The emphasis and the finite element mesh. is put on computational kernels, considering pre- and post- The attempts to define a new paradigm have continued processing as separate programs. Four fundamental modules for at least ten years [13, 17, 27] and have recently intensi- (subsystems) of computational kernels are identified for the fied (see e.g. articles in [3] and [16]). There are basically two four main tasks: problem definition, approximation, mesh approaches that can be found in literature. The first of them manipulation and linear system solution. Example interfaces are case studies of large, complex systems [5–8]. For such between the four modules that can accommodate a broad systems it is necessary to introduce some kind of modular- range of application areas, approximation methods, mesh ization of the program.
