Objectivies and Approach

The objective of the project is to formulate and improve mathematical models for certain problems in geosciences and to develop numerical methods and software packages for these, which can be implemented efficiently on parallel computers.

The problems will be formulated in mathematical form as two- and three-dimensional partial differential equations as used in elasticity and plasticity. The models will be written in numerical form and implemented on high performance computers. The software so developed will be tested on real sized problems and the tests will be analysed and compared with in situ observations and experience to make further improvements to the models.

Progress and Results

Theory, algorithms, benchmark test problems, and software related to the two major applications:

have been constructed. Thereby, the basic mathematical models from elasticity theory and elasto-plastic materials have been used, and finite element approximations have been derived. Several variants of solution methods for the arisisng linear and non-linear equations have been developed and analysed. Tests on the benchmark problems have been started for the purpose of comparisons. The methods are presently being implemented on various parallel computer platforms.

Information Dissemination Activities and/or Exploitation

Results of the project will be used by one industrial partner in designing new mine technologies, and by another in construction of highways, bridges and tunnels.

Besides workshops, a visit to one of the mine sites of Partner 6 is planned, where the practical application of the models developed, tested and recommended within the HIPERGEOS project will be demonstrated.
