Maximum number of iterations (linear solves) of the non-linear solver.
If a stagnation of the nonlinear solver is detected the solver stops. A divergence is reported by default forcing the end of the simulation. Setting this flag to 'true', the solverends with convergence success on stagnation, but report warning about it.

Convergence criteria is:\n\nnorm( res_n ) < max( norm( res_0 ) * r_tol, a_tol )\n\nwhere res_i is the residuum vector after i-th iteration of the solver and res_0 is an estimate of the norm of initial residual. If the initial guess of the solution is provided (usually only for transient equations) the residual of this estimate is used, otherwise the norm of preconditioned RHS is used. The default norm is L2 norm of preconditioned residual: P−1(Ax−b), usage of other norm may be prescribed using the 'option' key. See also PETSc documentation for KSPSetNormType.

Types of boundary conditions for heat transfer model.
Default heat transfer boundary condition.\nOn water inflow (qw≤0), total energy flux is given by the reference temperature 'bc_temperature'. On water outflow we prescribe zero diffusive flux, i.e. the energy flows out only due to advection.
Dirichlet boundary condition T=TD.\nThe prescribed temperature TD is specified by the field 'bc_temperature'.
Total energy flux boundary condition.\nThe prescribed incoming total flux can have the general form δ(fN+σR(TR−T)), where the absolute flux fN is specified by the field 'bc_flux', the transition parameter σR by 'bc_robin_sigma', and the reference temperature TR by 'bc_temperature'.
Diffusive flux boundary condition.\nThe prescribed incoming energy flux due to diffusion can have the general form δ(fN+σR(TR−T)), where the absolute flux fN is specified by the field 'bc_flux', the transition parameter σR by 'bc_robin_sigma', and the reference temperature TR by 'bc_temperature'.
