Development of a Web-Based Open Source CAE Platform for Simulation of IC Engines 2018-01-0473

CAE (Computer Aided Engineering) software have become an essential element in design, simulation, manufacturing and even marketing in the automotive industry as well as in other major manufacturing companies. Multiphysics simulation of IC engines may be one of the most challenging areas both technically and scientifically, since it requires sound basis and experience for diverse physical phenomena. There are quite a few commercial softwares currently available for various elements of CAE (Computer Aided Engineering), which require substantial investment cost for licensing, personnel and computing facilities. There is a current consensus for the need of low cost CAE based on open sources through which professionals may contribute to new modeling features and validation through a free access web-based platform. There are several high quality open sources available under GNU-GPL (General Public License) which allow free utilization and development. Some of them have features as competitive as their commercial counterparts, whereas their interface in general may not be as user-friendly as most commercial software. In this work we introduce a web-based platform with selected open source programs, FreeCAD for CAD, Code_Aster for FEA, OpenFOAM for Multiphysics CFD, MBDyn for multibody dynamics, Dakota for optimization together with Salome-Meca, cfMesh and snappyHexMesh and Paraview for pre and post-processing. All open source programs are downloadable, while remote job access and post-processing can be performed by cloud computing facilities. While the web site is currently under development through funding by KOSEF (Korea Science and Engineering Foundation), the performance will be shown for some example cases of in-cylinder flow, combustion, vehicle external flow, coolant channel flow and thermal analysis in an engine block.
