Structure

FEMatrix_Method module contains a lot of routine for constructing finite element matrices. You can think it like a snippets for element matrices.

• TODO add structure of FEMatrix_Method module in documentation.

Constructor methods

Mass matrix

$$\int_{\Omega } N^{I}\rho N^{J}d\Omega$$

STMass matrix

$$\int_{\Omega } N^{I}T_{a}\rho N^{J}T_{b}d\Omega$$ $$\iint \frac{\partial N^{I}T_{a}}{\partial t} \rho N^{J}T_{b}d\Omega dt$$ $$\iint \frac{\partial N^{I}T_{a}}{\partial t} \rho \frac{\partial N^{J}T_{b}}{\partial t} d\Omega dt$$ $$\iint N^{I}T_{a}\rho \frac{\partial N^{J}T_{b}}{\partial t} d\Omega dt$$
