Abstract
In this investigation, grid generation difficulties in CFD analysis of internal combustion engines (ICEs) have been studied. Grid generation is primitive, extremely complicated and time consuming task in ICEs simulations. The KIVA open source code is one of the most popular CFD solvers in ICEs simulations. Grid generation for this solver is the most complex and difficult task. In the present work a methodology has been developed for rapid grid preparation in KIVA-3V code by using commercial grid generator, ANSYS ICEM CFD. In this methodology, all geometry details of ICEs, including valves and intake/exhaust ports, are taken into account. In this paper, the focus is not on modifying the KIVA code original mesh generator, however, the most popular grid generation and dynamic mesh management errors and some bugs in ICEM CFD and KIVA have been inspected and explained. By using the procedure described here, many of grid generation difficulties will be eliminated and grid generation time will be greatly reduced. It should be noted that many of features in this paper are general and can be used for geometries other than ICEs.
