Abstract:
We present a new algorithm for combining a fully anisotropic goal-oriented
mesh adaptation with the transient fixed point method for unsteady problems.
The minimization of the error on a functional provides both the density and the anisotropy
(stretching) of the optimal mesh. This method is used for specifying the mesh for a time
subinterval from the state and the adjoint. The global transient fixed point iterates the
re-evaluation of meshes and the states over the whole time interval until convergence.
Applications to unsteady blast-wave Euler flows are presented.
