[15 Sept 2010] Pointwise reduces the time needed for high-fidelity CFD simulation of turbomachinery. In this webinar, we demonstrate the techniques used to create a multiple-block, structured mesh for the DARPA HIREP Axial Pump.

Reference: An Experimental Investigation of the Flow Through an Axial-Flow Pump by Zierke, et al. After linking to this document, go up one directory to find all the data.

Topics covered in this webinar include

Stop using block topology as a crutch and use smoothing techniques to achieve high quality.
Prevent erroneous or incomplete geometries from slowing mesh generation.
Set aside your fear of fillets and create structured topologies to handle them.
Reduce solver setup time by applying volume and boundary conditions for your solver.
