Parameters

[in]	geometry	contains all geometry quantities
[in,out]	profiles	contains profiles of plasma parameters
[in]	transport	contains profiles of trasport coefficients
[in,out]	sources	contains profiles of sources
[in,out]	numerics	contains all parameters required by run
[out]	diag	contains error messages and warnings

The boundary conditions for an equation in $Y$ are described by coefficients $\{V, U, W\}$ and they are on the form:

$V*Y' + U*Y = W$

Formulation of the differential equation for $Y(t)$ for a given $Y(t-dt)$ in terms of the coefficients $\{A, B, C, D, E, F, G\}$ in the SOLVER object.

$[A*Y-B*Y(t-dt)]/H + 1/C * [-D*Y(t)' + E*Y(t)]' = F - G*Y$
