Challenge Problems
Push your limits with advanced challenges
Given a grid where Δx = 0.05 m, Δy = 0.05 m, and Δt = 0.01 s, derive the CFL condition parameters for a wave speed of 300 m/s. Determine if the condition is satisfied.
💡 Hint: Focus on calculating each part, ensuring you respect the parameters set.
Apply the explicit finite difference method to find the displacement at the next time step for a given set of initial values un_i,j=2, un-1_i,j=1, un_i,j+1=3, and un_i,j-1=0. Define the neighboring contributions as well.
💡 Hint: Make sure to plug in all grid point values correctly and perform the appropriate calculations.
