English abstract:
This article discusses some aspects of nodal integration. It exhibits better convergence when applied to incompressible media, allows easier remeshing and reduces the number of integration points, thus, improving efficiency. Furthermore, understanding it may help to create new integration schemes in meshless methods as well. On the downside, it introduces non-physical low energy modes. The article focuses on elimination of these spurious modes.
