Abstract:V članku je predstavljen primer paralelizacije algoritma za izvajanje numeričnih simulacij. Algoritem temelji na metodi robnih elementov in je namenjen reševanju problemov iz dinamike tekočin. Za paralelno programiranjeje bil uporabljen MPI standard. Učinki paralelizacije na izračun kinematike ter tlaka so predstavljeni na primeru toka skozi kanal z valovito steno. Uporabili smo tri mreže različnih gostot z namenom primerjave pospešitve izvajanja programa.

Title:Paralelisation of numerical algorithm for simulating viscous fluid flow
Abstract:Article presents paralelisation of viscous flow solver algorithm. Algorithm is based on boundary element method and is used for solving fluid dynamics problems. It is composed of kinematic, kinetic and pressure computation part. For implementation of paralelisation MPI standard was used. Effects of paralelisation are shown on an example. We used three different meshes of different density with purpose of comparing acceleration of program execution.
