Table 3 Parameter choices for the implicit 2nd-order IMEX-RK component
Parameter | Property | Source |
|---|---|---|
λ = 0.24 | “Efficient” | [82] |
\(\lambda \geq \frac{1}{4}\) | A-stable | [76] |
\(\lambda = \frac{2 - \sqrt{2}}{2} = 1 - \frac{1}{\sqrt{2}}\) | L-Stable | [109] |
\(\lambda = \frac{1}{2}\) | Stiffly accurate | morgen, cf. [76, Sect. 5.1] |
\(\lambda = \frac{3 + \sqrt{3}}{6} = \frac{1}{2} + \frac{1}{\sqrt{12}}\) | Passive |
