Courant Number
Title
Question
What is the formula of the Courant number mentioned in tutorial 3?
What if I set it to an extremely small value even if it is not required for my simulation, will this affect the speed of the simulation or the memory consumption?

Answers:

Courant number is given by the following equation:

Co=u(Δt)/(Δx)
Here, Δt is the time step size, u is the velocity and Δx is the grid spacing

For extremely small courant number, your time step size will be very small which in turn will increase the simulation time
