Meshing or mesh generation discretizes a geometry surface or volume into multiple elements. Learn about high-order mesh generation using Fidelity Pointwise.
Refining your mesh should lead to a stable solution, very close to the continuous solution. If it is not case, it means you are not close to the real solution of the problem: your problem may be ill-posed or you have to refine more. There are error estimates, which computes the differ...
Smoothed-Particle Hydrodynamics (SPH) technology is a powerful alternative method to model complex transient flows with highly dynamic free surface flows. While the introduction of SPH into Simcenter STAR-CCM+ 2402 offers you integrated access to this method alongside the traditional mesh-based approach...
This is an exciting new addition and has applications across multiple industries including automotive, aerospace, pharmaceutical, and others. With the new nonconformal interfaces and sliding mesh capability, you can now study fluid flow on models with moving parts like this marine propeller simulation....
Stopping criteria based on response values can be used to avoid infeasible cases. And, to further speed up the time to solution and increase convergence robustness, previous design results can be used for initialization of subsequent sweep points in the study. Thanks to those smart sweeps ...
The metaverse refers to the convergence of physical and virtual space accessed through computers and enabled by immersive technologies such as virtual reality,augmented reality and mixed reality. Described by proponents as the next iteration of the internet, this3Dvirtual world is envisioned as a persi...
Slow convergence. Model instability. Poor skill. Teacher forcing is an approach to improve model skill and stability when training these types of models. What is Teacher Forcing? Teacher forcing is a strategy for training recurrent neural networks that uses ground truth as input, instead of model...
A problem where geometrical nonlinearity is the only source of nonlinearity will, in most cases, possess a unique solution for a certain load level. In this sense, it is possible to analyze the problem using a stationary analysis with a single load only. For convergence reasons, it is sometim...
part of the total computation time. We have reduced dramatically the computation time for most operations. Thanks to these improvements, the re-meshing frequency is increased, leading to a better mesh quality throughout the entire operation, and therefore better and faster convergence of the solver...
Stability and convergence of these strategies have been deeply investigated in literature, providing a solid theoretical framework to approximately solve differential problems. In this Section, the application of the novel methodology of PINNs on different typologies of Partial Differential models is ...
