Did you know?
WebI was wondering if there is a solver in matlab to simulate a transient 2D convection diffusion system of equations. The equations are of the form: du1/dt = D1 d²u1/dx² + d/dx (u1du2/dx) - Kdu1/dy. 0=D2 d²u2/dx². I tried pdepe but it is for 1D problems and solvepde but although i tried to add the convection term in f the solution is super ... WebJun 22, 2024 · It is possible to solve for \(u(x,t)\) using an explicit scheme, as we do in Sect. 3.1, but the time step restrictions soon become much less favorable than for an explicit scheme applied to the wave equation.And of more importance, since the solution u of the diffusion equation is very smooth and changes slowly, small time steps are not …
