I want to solve Lorenz system as a SDE with Wiener process added as noise. I was wondering if [this](https://diffeq.sciml.ai/stable/tutorials/sde_example/#Example-2:-Systems-of-SDEs-with-Diagonal-Noise) is the correct way to represent this problem ? According to my understanding, the diagonal noise added here has the same properties of Wiener process (i,e. N(0,dt)). Am I mistaken?

Yes that’s what it is.
