Ansys student products can be installed on any supported ms windows 64bit machine. As far as i understood, i can select any of the points in my domain as a point corresponding to one of the gauss point say of 5x5 matrix points, and then can use coordinate transformation to select the other points. Gauss points are good because there are more per element than nodes and calculations are done at the gauss points anyhow. To explore ansys software suites, select one of the areas of interest below.
