Web21 de jan. de 2024 · Table 2: The selection of time-dependent behavior of the problem should be appropriately selected for the numerical schemes. The first order bounded, ‘Euler’ is the most robust while the second-order ones are more accurate. Backward is a second-order time-differentiation scheme that gives higher accuracy but may reduce stability.
