Hi all, I am using the following code to solve an ODE. I defined my variables but I am still getting an UndefVarError. Any help here? v_x(x, y, t) = -sin(pi * y) * cos(pi * t / 5) v_y(x, y, t) = sin(pi * x) * cos(pi * t / 5) p = 0 # we assume u is a 2 x num_particles matrix function rhs!(du, u, …

Getting UndefVarError even though variables are defined

you need to define p before this line
