Auxiliary solver FindOptimum using for two variables

Post by annier »

Hi All,
Can the Optimization solver applied to the coupled sets of variables T and v for solving Heat Equation and Navier Stokes equation?

Hi annier

The FindOptimum only provides some routines to optimize design variables. You must yourself define the cost function. In principle there is no limitation in coupling. However, the case can not be transient since the internal optimization uses the "scanning" level as the iteration loop.

As an example of multiphysics optimization there is a test case: fsi_beam_optimize. One keypoint here was to use smooth mesh deformation with small number of parameters for the shape optimization. Something similar could be done for thermal flow as well.
