{h}\)are the discrete, finite-dimensional trial and test spaces, respectively. In this work, we follow the Continuous Galerkin (CG) approach with first-order basis functions, which provides standard linear Lagrange elements, e.g., a triangle with nodes at the three vertices of each element ...
Then, actual experiments were conducted to validate the method by our self-designed platform and other relative facilities. During the process, orthogonal experiments and corresponding analysis method were employed to seek an optimal parameter combination. As for the four important parameters, the number...
