PoissonPDEComponent
PoissonPDEComponent[vars, pars] yields a Poisson PDE term ∇²u - f with model variables vars and model parameters pars.
Examples
Create a Poisson equation component:
PoissonPDEComponent[{u[x, y], {x, y}}, <|"LoadValue" -> 1|>]Solve Poisson's equation on a disk:
eqn = PoissonPDEComponent[{u[x, y], {x, y}}, <|"LoadValue" -> 1|>];
NDSolveValue[{eqn == 0, DirichletCondition[u[x, y] == 0, True]},
u, {x, y} \[Element] Disk[]]Visualize the solution:
sol = NDSolveValue[{eqn == 0, DirichletCondition[u[x, y] == 0, True]},
u, {x, y} \[Element] Disk[]];
