JasmineFeng New Member Jasmine Feng Join Date: Feb 2023 Posts: 14 Rep Power: 3	I am confused about how to choose an appropriate value of $\alpha$ in the artificial viscosity. The value that I deduced is far from the recommended value and led to great numerical instability. $\Pi_{ij}=-\alpha h\frac{c_i+c_j}{\rho_i+\rho_j}\boldsymbol{b}_{ij}$ Last edited by JasmineFeng; October 14, 2024 at 23:06.
