WebPeriodic fluctuation as the main unknown¶. Instead, we will keep the initial formulation and consider the periodic fluctuation \(\boldsymbol{v}\) as the main unknown. The periodicity constraint on \(\boldsymbol{v}\) will be imposed in the definition of the associated FunctionSpace using the constrained_domain optional keyword. To do so, one must … http://geuz.org/pipermail/gmsh/2016/010306.html WebGmsh is an open source 3D finite element mesh generator with a built-in CAD engine and post-processor.
