WebPDE-constrained optimisation problems are problems of the form: min u, m J ( u, m) subject to F ( u, m) = 0 l u ≤ m ≤ l b g ( m) ≤ 0. where m contains the optimisation variables, J is a real valued objective functional, F ( u, m) = 0 is the PDE with solution u. The bounds and inequality constraints can be used to restrict the feasible ... WebMeshFunctionSizet¶ class dolfin.cpp.mesh.MeshFunctionSizet (*args) ¶. Bases: dolfin.cpp.common.Variable, dolfin.cpp.mesh.HierarchicalMeshFunctionSizet A MeshFunction is a function that can be evaluated at a set of mesh entities. A MeshFunction is discrete and is only defined at the set of mesh entities of a fixed topological dimension.
