@xtalax can the brusselerator problem use MOL?

DiffEqProblemLibrary.jl/lib/ODEProblemLibrary/src/brusselator_prob.jl

Lines 100 to 103 in 0afb033

	const D_brusselator_u = CenteredDifference{Float64}(2, 2, 1 / (N_brusselator_1d - 1),
	N_brusselator_1d)
	const D_brusselator_v = CenteredDifference{Float64}(2, 2, 1 / (N_brusselator_1d - 1),
	N_brusselator_1d)

[xtalax]

yes, we have a bruss example in the tests

[xtalax]

this should stay in the problem library though, important to keep examples around

[vpuri3]

can we do it without DEO?

[vpuri3]

let's remove the brusselator problem from this package temporarily. we should redo it with methodoflines.

[ChrisRackauckas]

Add the bruss from https://docs.sciml.ai/DiffEqDocs/stable/tutorials/advanced_ode_example/
