Multiblock Grid Generation. Part 2. Multiblock Aspects

摘要

Block-structured-grid-based methods offer a viable choice for solving viscous211u001eflows over complex aerodynamic configurations. Body-fitted structured grids are 211u001ewell suited for resolving the thin viscous layers developing in the vicinity of 211u001esolids surfaces at high Reynolds numbers typically encountered in flight. A state-211u001eof-the-art structured flow solver, like ENSOLV, is very efficient in computing 211u001eaerodynamic flows in the presence of such embedded boundary layers. An important 211u001estep in routine application of structured-grid methodology to CFD applications is 211u001ethe grid generation process. At NLR and Fokker this is done with ENDOMO and 211u001eENGRID. The design of the domain decomposer ENDOMO and grid generator ENGRID has 211u001ebeen realized in close relationship between an NLR CFD team as supplier and 211u001eaerodynamic design and research teams from Fokker and NLR as customer. The 211u001epartnership between the CFD development team and the design teams has led to user-211u001efriendly GUI based on concepts that automate much of the low level grid 211u001egeneration tasks.
