Abstract.We are interested in introducing a new computational framework to
decrease significantly the cost of simulation for time dependent thermal,
thermoelastic and thermoelastoplastic problems that arise in particular in
the simulation of welding or additive manufacturing. For that purpose we
use Isogeometric Analysis, weighted quadrature and matrix free approaches
that have been introduced with other types of problems. We will focus in
particular the talk on the introduction of a cheap preconditioned, based on
the Fast Diagonalisation method that exploits the tensor product structure
of the IGA basis functions. We will show that our preconditioner offers
efficiency, cost effectiveness and simplicity in implementation.
Furthermore, it exhibits robustness concerning polynomial degree and mesh
size parameters. We will address both transient heat conduction problems
with variables coefficient, as well as linear elasticity with some
preliminary extensions to elastoplasticity.
