Capable of generating structured, unstructured, and hybrid meshes, Pointwise v17.3 R4 includes open source PyFR advection-diffusion solver as native interface. Program also includes support for Engineering Sketch Pad, an open-source, browser-based, constructive solid, CAD system. ESP targets multi-disciplinary analysis and optimization by aiding computation of sensitivity of objective functions (lift and drag, for example) with respect to design parameters (wing sweep, for example).
