Direct and discretized perturbations revisited: A new error source interpretation, with application to moving boundary problem

It is well-known that qualitative and/or quantitative differences will be possibly induced, when applying direct (i.e., attacking directly the partial differential equations) or discretized (i.e., using a low-order Galerkin truncated model) perturbation methods to nonlinear structures using multi-sc...
