One for all – the new SAMG solver control within FEFLOW
نویسنده
چکیده
The use of an efficient linear solver is very important to reduce the overall runtime of a flow simulation. However, if a linear solver will be very fast e.g. in case of a time dependent model it does not have to be efficient in case of a steady-state model. The efficiency of the linear solver may even change during a simulation run. Hence, there is the need to develop a solver control which chooses an appropriate linear solver for each respective situation. This paper describes the new SAMG solver control available with FEFLOW version 5.4. Numerical results are presented for a range of industrially relevant models, demonstrating the robustness and efficiency of the new solver control.

Algebraic Multiscale Linear Solver for Heterogeneous Elliptic Problems a Report Submitted to the Department of Energy Resources Engineering of Stanford University in Partial Fulfillment of the Requirements for the Degree of Master of Science
An Algebraic Multiscale Solver (AMS) for the pressure system of equations arising from incompressible flow in heterogeneous porous media is developed. The algorithm allows for several independent preconditioning stages to deal with the full spectrum of errors. In addition to the fine-scale system of equations, AMS requires information about the superimposed (dual) coarse grid, which is used for...
متن کاملUse of MT3DMS for Heat Transport Simulation of Shallow Geothermal Systems
The multi-species transport model MT3DMS is applied to simulate heat transport in shallow confined aquifers. This is done by taking advantage of the mathematical similarities between the description of heat and solute transport. A comprehensive analysis on the applicability of MT3DMS (version 5.2) for heat transport simulation of closed shallow geothermal systems is shown. MT3DMS simulations ar...
متن کاملA preconditioned solver for sharp resolution of multiphase flows at all Mach numbers
A preconditioned five-equation two-phase model coupled with an interface sharpening technique is introduced for simulation of a wide range of multiphase flows with both high and low Mach regimes. Harten-Lax-van Leer-Contact (HLLC) Riemann solver is implemented for solving the discretized equations while tangent of hyperbola for interface capturing (THINC) interface sharpening method is applied ...

This research focuses on proposing an optimal trajectory planning and control method of two link rigid-flexible manipulators (TLRFM) for Dynamic Object Manipulation (DOM) missions. For the first time, achievement of DOM task using a rotating one flexible link robot was taken into account in [20]. The authors do not aim to contribute on either trajectory tracking or vibration control of the End-...
