[en] This paper presents a new adaptive scheme for the error-controlled simulation
of transient dynamics problem. We rely on spline bases for the higher-order
spatial description of our kinematic fields. Local adaptivity is performed by
employing a hierarchical T-mesh technology, in combination with geometry independent field approximation. The Newmark
algorithm is chosen to solve the semidiscrete equation of motion. We will present
some simple local error estimates to drive the adaptivity, and show how we can
ensure that the mechanical energy of conservative systems is preserved during
the refinement process.
