The Meshy Award competition was instituted by Pointwise this year to recognize the artistry and technical skill of Pointwise and Gridgen users.
Dr. Böttcher’s meshes were generated in conjunction with a project involving steam generators and pumps for a power plant. The model represents the pressure vessel (RPV) of a power plant including its four primary loops and components like pipes, steam generators and pumps. The internals of the pressure vessel – with exception of the fuel pins – are resolved in all details, while the components of the primary loops (steam generators and pumps) are treated as porous media models in terms of volumetric sources and sinks. The overall hybrid mesh contains about 35,000,000 cells with scale resolutions of 150 mm inside the steam generators down to 1 mm spacing inside the RPV.

Dr. Böttcher has been working in computational fluid dynamics (CFD) since 2001, including projects such as modeling of chemical reactors, nuclear pressurized water reactors, liquid metal flows (lead-cooled systems) and multiphase flow phenomena (boiling water reactors). He previously did stratospheric ozone research at the Institute of Meteorology at Free University of Berlin and was a scientific assistant at Hermann-Föttinger Institute at Technical University of Berlin. The topic of his doctoral thesis was “Numerical Simulation of Turbulent Shear Layers by Using a Discrete Vortex Method” and he earned his Ph.D. in 1990.
