CFD Online Discussion Forums - Is there a global container where all Function1 are stored?

Hello,

for a plugin I need an way to manipulate a Function1<scalar> value each time step. I knowing the type of Function1, the patches of interesset and the boundary condition.

BC: externalWallHeatFluxTemperatureFvPatchScalarField
The function1 for the heat flux is stored in local private member q_. The function1 is of type constant for that example.

The way as shown in followed code is not possible. So, perhaps it is a global storage of all Function1-Objects with corresponding patchIds.
Do have OpenFOAM an global Function1-Storage?

Code:

// get T field

auto T_ = const_cast<volScalarField*>(&mesh.lookupObject<volScalarField>(nameTField))



// get bc for path with Id

auto bPatch = refCast<const externalWallHeatFluxTemperatureFvPatchScalarField>(T_->boundaryField()[patchID]);



// how to access the q_ Function1<...> of patch ...?

bPatch.q_[0] = 1.0;
