Early Stage Researcher 6 at ESI

Node based parametrisation

Note: This position has been filled.

In continuation to developments achieved in the About Flow project, the ESR at ESI will focus on the industrialisation of the adjoint based optimisation tools. Three major activities are foreseen:

• Innovative approach for volumetric mesh morphing and its extension towards CAD-free parametrisation including handling of geometric constraints,
• Finite difference based approach to update CAD geometries and
• Utilisation of immersive virtual reality environment for analysis adjoint based optimisation results.

Objectives:

• M1-M12: implementation of a CAD-free surface parametrisation based on smooth constraints & integration in in-house mesh morpher. Adaptive selection of control points based on local geometrical features (typically curvature). Handling of simple geometrical constraints (box) Integration in the ESI i-adjoint morpher. Validation & evaluation (WP1,2,4,6)
• M12-M20: Immersive visualisation of adjoint results within IC.IDO including sensitivity maps & adjoint states. Possibility of visualising shape deformation as recommended by the adjoint solver in real-time will be investigated. Implementation of a demonstrator on test case of WP1. Secondment to VW (WP1 & 6)
• M20-M36: FD-based CAD gradient from surface node sensitivity using the approach based on discrete harmonic mapping to a reference patch. Development of the harmonic and inverse harmonic mapping within ESI adjoint kernel. Automation of invariant point selection. (WP3,6). Integration into a workflow involving OpenCascade (OCCT) as the geometric modeller, Secondment to OCC  (WP3 & 6)
