A semi-implicit finite element scheme with multigrid acceleration for high-viscosity non-Newtonian flows

Key Points

• This approach significantly enhances computational efficiency in simulating high-viscosity non-Newtonian flows, enabling faster results for complex scenarios.
• The semi-implicit finite element scheme was shown to outperform traditional methods in terms of stability and convergence rates across various test cases.
• Assessment included simulations of typical non-Newtonian fluids, focusing on flow behavior and response under different viscosity settings.
• These findings highlight the potential for broader applications in engineering problems where non-Newtonian behavior is critical, suggesting efficient numerical strategies.
