The Moving Finite Elements project hosts a collection of simulation codes for time-dependent PDE systems that implement various forms of Keith Miller's gradient-weighted moving finite element (GWMFE) method. The Calliope sub-project aims to provide new reference implementations in modern object-oriented Fortran. Click on the Calliope tab on the main project menu bar.
Sandia National Laboratories’ (SNL) environmental assessment modeling tool helps optimize the design of MHK-turbine array layouts within ocean, tidal, and river systems to balance energy generation efficiency with environmental considerations. The new tool, SNL-EFDC, is an augmented version of US EPA’s Environmental Fluid Dynamics Code (EFDC) and includes; (1) a new module that simulates energy conversion (momentum withdrawal) by MHK turbine-like devices including commensurate changes in the turbulent kinetic energy and turbulent kinetic energy dissipation rate, (2) new, advanced sediment dynamics routines, and (3) augmented water quality modules. SNL-EFDC has been verified and validated against flume measurements of flow around sub-scale turbines and actuator disks.
This script fills in a two dimensional surface with an unbroken, non-overlapping path. The path direction is random, so one can imaging a chess board filled with dominos, with the constraint that the layout of the dominos is complete (board is filled) an
