The mesh must meet minimum quality requirements: a poor mesh will increase computation time, decrease accuracy and, in case of excessive element deformation, prevent convergence. A significant factor in obtaining an accurate solution is the use of well-shaped elements and of an appropriate mesh ...
In addition to an approximation based on the transit time of a dilatational wave over the shortest element dimension of the system [241], a convergence test can be conducted to determine the calculation time step to guarantee the simulation results to be independent of the time step [214, 242...
Generators serve as the heart of hydroelectric power plants and must be accurately designed to optimize energy output and prevent excessive temperatures that cause energy losses and shorten the machine’s life. Leveraging Ansys simulation and an improved workflow, INDAR engineers improve generator design...
Robust 3D mesh watermarking is a traditional research topic in computer graphics, which provides an efficient solution to the copyright protection for 3D meshes. Traditionally, researchers need manually design watermarking algorithms to achieve sufficien
We present an algorithm for hp-adaptive collocation-based mesh-free numerical analysis of partial differential equations. Our solution procedure follows a
In adaptative grid refinement, we expect the boundary layer and the near-wall physics to be preserved, and there is smooth gradation in cell sizes, ensuring solver convergence. During adaptation grid refinement, it is necessary to define an adaptation sensor, describing th...
This satisfies P i αi →∞, and αi → 0 as i →∞, and en- sures convergence. Our evaluation uses multiplicative increase and multiplicative decrease, and we plan to compare it with additive increase and additive decrease in the future. while (not converged and i < maxIterations) i ...
FIG. 37 illustrates a convergence test for the computed temperatures in the one dimensional slab of FIG. 36, wherein the temperature distributions are computed at the same time point using a different time step and different degrees of freedom. FIG. 38 illustrates the sensitivity of the stress ...
