WebJul 15, 2024 · Solving nonlinear PDE in Python with LSODA. I am attempting to solve a nonlinear diffusion equation of the form ∂ t u = ∂ x ( κ ( u) ∂ x u), where the conductivity function κ ( u) is a power law κ = u 5 / 2, using the LSODA time integrator in Python interfaced through SciPy. The equation is discretized by finite difference on a spatial ... Web2 days ago · When I ran scipy.integrate.solve_ivp outside the objective function, it took about 6 mins. However, when I ran the same code inside the objective_function, it took much longer than that. I tried to track the t by printing t while running, and I found that delta t (from solve_ivp ) is much smaller when it was run inside the objective_function (0.00000001 < …
