Numerical simulation of nonlinear poromechanics

Storkaas (2005) present a relatively simple first principle-based model which captures the main dynam- ics of a severe slugging flow regime (Storkaas et al., 2003) in

Design suitable nonlinear estimators (non linear versions of the Kalman filter or non linear observers) using the nonlinear ODE model of the flow through a

Again, LS wastes no iterations, and uses approximately the same number of iterations as the successful Newton steps and slightly fewer residual evaluations overall..

The rest of the paper is organized as follows: The class of BGNLMs is mathematically defined in Section 2. In Section 3, we describe the algorithm used for inference. Section

Using this exhaustive data set, numerical modeling of the tsunami has been conducted using both a nonlinear shallow water model and a Boussinesq-type model that includes

This method is of interest for (i) the flexibility to use different time steps for flow and mechanics (ii) the advantage to derive error and a posteriori error analysis, permitting

As we have seen, for a single Riemann problem it is possible to derive å priori the explicit expression for the residual flux term /reB - This was first observed by Espedal and

Generalizations of Eulerian-Lagrangian localized adjoint methods (ELLAM) to non linear advection-diffusion equations in one space dimension are considered.. Diffusion is modeled
