“In our group we have performed computations of flow

around aircraft and wind turbine blades using FINETM Hexa. For these challenging applications we were very pleased

with FINETM/Hexa’s capabilities, three of which we would like to mention especially. To begin with, the automated mesh generation was fast and took little effort of the user. Secondly, the flow feature adaptation allowed us to obtain accurate results with a reasonable number of grid points. Finally, the agglomeration multigrid technique proved to be a significant convergence accelerator, often resulting in a speed-up of a factor of five.” Dr. Hester Bijl, Associate Professor, Faculty of Aerospace Engineering,
