Which consequence results when the viscosity term is omitted from the Navier-Stokes equations during simulation of a mixed fluid?

💡 Explanation

Omitting viscosity eliminates dissipation; therefore, energy accumulates unphysically via nonlinear terms, leading to numerical instability because the equations become ill-posed. This results in divergence, rather than allowing for accurate pressure profiling or stable solutions.
