From 23, 25 and 26 of March, Johan Jansson (BCAM researcher) will visit ITMATI to give the couse: "Automated finite element computing in the FEniCS framework".
Basic laws of nature are typically expressed in the form of partial differential equations (PDE), such as Navier's equations of elasticity, Maxwell's equations of electromagnetics, Navier-Stokes equations of fluid flow, and Schrödinger's equations of quantum mechanics. The Finite element method (FEM) has emerged as a universal tool for the computational solution of PDEs with a multitude of applications in engineering and science. Adaptivity is an important computational technology where the FEM algorithm is automatically tailored to compute a user specified output of interest to a chosen accuracy, to a minimal computational cost.
Developing multiphysics finite element methods (FEM) and scalable High-Performance Computing (HPC) implementations can be very challenging in terms of software complexity and performance, even more so with the addition of adaptive error control. To manage the complexity we in this course will learn about general adaptive methods and the FEniCS automated open source software framework taking the weak form of the PDE as input in near-mathematical notation and automatically generating low-level source code for assembling tensors and a posteriori error estimates and indicators for adaptive error control. Other key concepts in the course are automateddifferentiation for treating non-linear problems and a transparent and scalable HPC implementation.
We will demonstrate the concepts in the course on a range of applications, and analyze a large-scale application to adaptive computation of aerodynamic forces on a full aircraft at take-off and landing with good match to experiments.
The practical part of the course will require the use of the Simtek platform; PCs in the computer rooms will be ready to connect to Simtek. If anybody want to bring his own laptop, he must check whether ParaViewWeb (http://paraviewweb.kitware.
