FEM and hp-FEM

Live presentation of the example “lshape" from Hermes2D examples suite.

Flame propagation

Microwave heating

Thermally-conductive flow

Hermes project

2004 – present.

Goals:Provide stable platform for development of adaptive hp-FEM solvers.

Disseminate adaptive hp-FEM to practitioners.

Unique features:All algorithms PDE-independent.

Adaptive hp-FEM for time-dependent problems.

FEMhub project

Started in Spring 2009.

Goals:Provide open source distribution of FEM codes with unified Python interface.

Define model once, solve using various FEM codes.

Integrate open source FEM tools:mesh generatorsvisualizersweb notebook for remote computing. . .

Create certification procedure for open source FEM codes.
