In general, you can also force the momentum equations in grid-point space by writing into `u_tend_grid` and `v_tend_grid`. -(Not needed anymore with SpeedyWeather.jl v0.8) -~~Then one last detail is the call to `spectral_truncation!`. Despite the -triangular spectral truncation in SpeedyWeather, the lower triangular matrices -for the spherical harmonics are actually of size ``N+1 \times N``, because -this additional degree (=row) is needed for vector quantities -(see [One more degree for spectral fields](@ref)). Here particularly, -this means that the last spectral transform will compute the spherical -harmonics of this last degree which, however, scalar quantities like -vorticity should not make use of. We therefore set this degree to zero -with the call to `spectral_truncation!`, which does exactly that.~~ - ## Custom forcing: model construction Now that we have defined a new forcing, how to initialize it and what
