Abstract:

Development of solution algorithms for complex flowfields is the continuing objective of the research. The physical events are used to determine appropriate subdomains for both preselected and adaptive divisions of the field. Adapted embedding procedures have been completed for two-dimensional Euler flow with considerations of most suitable decision parameters. Development of an algorithm which combines cell and nodal-centered features continues for applications to less restrictive embedded topology. A mixed implicitexplicit approach for different coordinate directions is under study for Navier-Stokes flow. The Dec. 1984 Jerusalem Workshop is summarized briefly. Keywords Euler equations Embedded grids Adaptive grids Airfoils and Computational Fluid Dynamics.
