October 1, 2017, 11:02	Implicit nonlinear source term?	#1
OmarEGB New Member Omar E. Godinez Join Date: May 2016 Posts: 8 Rep Power: 10	Hello all, I am having difficulties dealing with custom solver I am working with. One of the equations is a Poisson-Boltzmann equation, of the form fvm::laplacian(psi)==sinh(psi) is there any way to specify the left hand side to be solved implicitly when it is nonlinear? I mean using something like fvm::Sp(1.0, psi) I would appreciate any help.
