— DAKOTA® coupling, optimization, simpleFoam, steady-state, function objects —
The coupling of DAKOTA® and OpenFOAM® is a common strategy if optimization tasks have to be performed automatically. However, most engineers do not use optimization toolboxes, and test cases that demonstrates the coupling are rarely documented or out of date. This case demonstrates how to set-up the interface for DAKOTA®. As always, the well-structured and commented run script from Tobias is used to give all essential information about the operations. The case itself models the Tesla's One-Way-Valve. Here, the channels are designed in a way that the flow can pass easily in operation direction, while the reverse flow will reduce the mass flux based on the geometrical design. The task for the optimizer is to find the pressure drop in which the reverse flow has three times less mass flux than the »opened« direction.

gThe available training cases are tested and built for different OpenFOAM® versions. During the tests, only the OpenFOAM Foundation version of OpenFOAM® was used. Furthermore, the following software packages are required for most of the training cases: Salome®, ParaView®, and for optimization tasks one also needs DAKOTA®. The cases might work with the ESI version of OpenFOAM® too (not tested). Additionally, there is no support for Windows-based OpenFOAM® versions.
