Kyokai.F–A Small Thermal Flow Solver

The paper discribes further development of a small user-friendly boundary element - finite element computer program KYOKAI. F for the numerical modelling of two-dimensional viscous and thermal fluid flows in unsteady state. The program is dedicated especially for the interactive use on super-mini, and its structure and pre-post procedures are presented. The usefulness is shown by worked examples by the boundary element method.
