Error indicators for controlling automatic grid refinement in ISIS-CFD
نویسندگان
چکیده
This master’s thesis work is a part of the effort to build various error indicators or refinement criteria for the adaptive grid refinement part of the ISIS-CFD flow solver. The purpose is to develop such refinement criteria which respond to the needs of the flow solver users and are general and flexible. Three types of refinement criteria are tested for various flow and refinement conditions. We focus here on the capturing of vortices to observe the performance of refinement criteria. Two test cases are used for this purpose. The work is done on the initial stages and more in-depth analysis of the refinement criteria is proposed in order to use them efficiently.

Computation of Free-Surface Viscous Flows around Self-propelled Ships with the Help of Sliding Grids
Accurate prediction for a self-propelled ship is a challenging task for CFD computation. While turbulence modeling is a crucial issue, more physical modeling is involved in a propeller simulation: transition, cavitation, turbulence, ventilation, etc. More advanced numerical technique is also required to capture very small scale flow motion such as tip vortex. The ISIS-CFD RANSE code has been fu...

Most grid optimization methods for the boundary element method are based on a postieri error indicators and error estimators. The error indicators are a local estimate of error within each boundary element. The error estimator provides a global bound on the error and is calculated from the error indicators. Typically, a problem is run on a coarse grid and the local error indicators are calculat...
