A Derivative-Free Mesh Optimization Algorithm for Mesh Quality Improvement and Untangling [PDF]
Mathematical Problems in Engineering, 2015 We propose a derivative-free mesh optimization algorithm, which focuses on improving the worst element quality on the mesh. The mesh optimization problem is formulated as a min-max problem and solved by using a downhill simplex (amoeba) method, which computes only a function value without needing a derivative of Hessian of the objective function ...

Large-Scale CFD Parallel Computing Dealing with Massive Mesh
Journal of Engineering, 2013 In order to run CFD codes more efficiently on large scales, the parallel computing has to be employed. For example, in industrial scales, it usually uses tens of thousands of mesh cells to capture the details of complex geometries.

3D finite element modelling optimization for deep tunnels with material nonlinearity
Underground Space, 2018 3D modeling of tunnels using a nonlinear ground model is still a time-consuming task because it usually requires a large number of incremental phases with iterative processes, to ensure accuracy while minimizing computational effort.
