RBF Morph

RBF Morph

This video was recorded at PRACE Autumn School: Industry Oriented HPC Simulations, Ljubljana 2013. An overview about mesh morphing and its benefits was given with a specific focus on Radial Basis Functions (RBF) methods and the industrial tool RBF Morph, currently available as an add-on for the CFD solver ANSYS Fluent. Standard applications of mesh morphing was first explained; the tool is here used as an effective way to makes the original CFD model parametric with respect to the shape. Details on how such parametric models can be introduced in typical industrial workflow (shape or set-up optimization) was given including CAD connection (STL targets and back to CAD) and flow sculpting (using adjoint solver of Fluent). Advanced applications was covered as well including: fluid structure interaction using 2-ways FSI and modal superposition, ice/snow accretion modeling, transient morphing with desired time histories.
