The G -equation is a standard leve l set equation containing the advective\, normal\, and mean curvature term s. Compared to conventional algorithms to solve level set equations on a p olyhedron mesh\, the proposed scheme has mainly three advantages. The firs t is that it numerically shows higher order of convergence on polyhedral m eshes. The second is that the implementation of parallel computing using d omain decomposition with 1-ring face neighborhood structure can be done st raightforwardly by a standard cell-centered finite volume code. The third is that a time step restriction caused by the CFL condition is reduced by the proposed semi-implicit scheme. Numerical examples computed on polyhedr al meshes are presented to verify the numerical properties of the proposed algorithm in the case of each velocity term in the G-equation.\n LOCATION:https://researchseminars.org/talk/MathMAC/58/ END:VEVENT END:VCALENDAR
