abstract = "We present an efficient adaptive numerical scheme for parabolic
partial differential equations based on a finite volume (FV)
discretization with explicit time discretization using embedded
RungeKutta (RK) schemes. A multiresolution strategy allows local
grid refinement while controlling the approximation error in
space. The costly fluxes are evaluated on the adaptive grid only.
Compact RK methods of second and third order are then used to
choose automatically the new time step while controlling the
approximation error in time. Non-admissible choices of the time
step are avoided by limiting its variation. The implementation of
the multiresolution representation uses a dynamic tree data
structure, which allows memory compression and CPU time reduction.
This new numerical scheme is validated using different classical
test problems in one, two and three space dimensions. The gain in
memory and CPU time with respect to the FV scheme on a regular
grid is reported, which demonstrates the efficiency of the new
method.",
