A discussion on issues relating to multiblock grid generation
Abstract
Efforts aimed at bringing a multiblock grid generation system to the state of maturity necessary for practical use are discussed. Attention is focused upon the interrelated areas of topology generation and grid control. An algorithm for automatically decomposing a flow domain about an aircraft configuration into a componentadaptive topology is given. Two techniques for controlling the resulting grid topology are described. The first automatically produces default grids, which will generally be of an acceptable quality. The second is a userfriendly interactive grid editor which allows any deficiencies in the default grids to be rapidly identified and modified. Examples of the multiblock approach are applied to a range of aircraft geometries.
