Treatment of C0-solutions of transient two-phase flow by the ASWR-method

During the past few years, Weighted Residual (WR) Methods have been introduced to the solution of fluiddynamic problems in nuclear engineering. Among the many possible WR-methods, separated region methods, using separate spaces for test- and weighting functions (ASWR) are particular attractive for the solution of hyperbolic problems. Due to the flexibility of this particular kind of WR-methods, phenomena typical for fluiddynamic problems, like discontinuities of derivatives can be treated accurately and efficiently. This paper describes the latest stage of the development of a general purpose fluiddynamics code utilizing the ASWR-method. On this version the problem of calculating C/sup 0/-solutions was resolved in an efficient way
