Description

Example for the optimisation of the Weertman friction coefficient using the vectorised incompressible Stokes solver (IncompressibleNSVec).

This is a twin experiment where we try to recover the true friction coeffcient, using the solution computed with the model as target.

Run the example

1. Make mesh

   ElmerGrid 1 2 rectangle
   

2. Generate solution

       ElmerSolver Direct_nl.sif
       ```
   
   

3. Run the optimisation

       ElmerSolver OPTIM_TWIND_nl.sif 
       ```
