The ZZ-type error indicator has also been employed in the context of mesh-free solutions of elasticity problems using the mesh-free Finite Volume Method [23] in both weak and strong form using the Finite Point
Because HPC resource is easy to access, even an FYP student may try to solve 10-20 million cells CFD problems. In the eyes of most CAE users, large cell count means high fidelity and therefore all physics can be resolved. This is not true, becausesome physics must be modelled. For exa...

In higher dimensions a wide range of singularities may appear in the solutions of singular perturbation problems. These singularities can be caused by, for example, a lack of smoothness in the data, irregularities in the geometry of the domain or the presence of mixed derivatives in the ...
In this work, we show that solving the time-dependent adjoint equation and using a suitable inner product with the forward solution allows more precise refinement of the relevant waves. We present acoustics examples in one and two dimensions and a tsunami propagation example. To perform these ...
you may face problems with incompatibility of channel properties. For example, the transmission timing may not allow you to send the amount of data necessary for your algorithm to perform properly. Also, the payload size that the network can work with on a new medium may be so small as to...
This creates another problem in that a huge number of reduced problems exist with solutions that cannot usually be found by a gradient-based optimizer in the full design space. Stress constraints for a partial domain of the structure are not allowed because they often create an ill-posed ...
The possibility of using modern parallel machines even for unstructured mesh based programs implies the necessity of dealing with two problems: the former lies on the strategies and algorithms that can be used for the partitioning of the grid and the mapping of the subdomains among the processors;...
This normally leads to both accurate solutions and better convergence for the numerical solution methods. Figure 3.9 illustrates an example of a mesh consisting of quadrilateral elements near the walls and triangular elements for the rest of the flow domain. Note again the idea of a ‘stretched’...
Comparing mesh WiFi to routers and repeaters is like comparing apples with oranges. Put simply, which is best depends on your needs. For example, for a single-floor apartment that has heavy and high-traffic internet use, such as gaming, streaming and large data transfers, traditional routers ...
