Developing an advection scheme for Telemac-2D based on the 2nd order characteristics method, 8th Telemac User Club, Chatou, 15-16 November 2001.

One of the best method of improving the accuracy of the advection scheme based on method of characterictics is to improve the interpolation of advected variables on the feet of the traced-back characteristic curves. The results of applying the second order interpolation in broader element patches are compared with the presently applied single-element linear interpolation and the SUPG method. Continue reading

Comparing numerical simulations of free surface flows using non-hydrostatic Navier-Stokes and Boussinesq equations

Jean-Michel Hervouet and Jacek A. Jankowski

Abstract. The numerical solutions of three-dimensional, non-hydrostatic Navier-Stokes equations are compared to the ones obtained with Boussinesq equations in the case of a solitary wave in a rectangular channel. Continue reading

The article describes the hands-on experiences by changing the principal supercomputer architecture from the vector to the parallel one, connected with the purchase of a shared-memory parallel SGI Origin 2000 machine by BAW for its Karlsruhe site. Continue reading

Telemac 5.0 — Eine konservative Revolution

Jacek A. Jankowski and Jean-Michel Hervouet

Telemac 5.0 — Eine konservative Revolution. Supercomputing News 4/1999, BAW Hamburg.

The article describes the re-implementation of the Telemac system software from Fortran-77 to Fortran-90 and changes in the code due to the much larger possibilities of the newer programming language.

A threedimensional non-hydrostatic model for free surface flows – development, verification and limitations

Holger Weilbeer, Jacek A. Jankowski and Werner Zielke

Abstract. The theoretical background of a new finite-element non-hydrostatic model for simulation of free surface flows based on the fractional step method and pressure decomposition is presented. Continue reading
