Hydrostatic pressure loads for a tank using “CID Distributed Loads” fields in a PATRAN FEM model

The purpose of this paper is to present a practical way to introduce distributed loads on the walls of a tank in order to perform a FEM analysis using PATRAN/NASTRAN programs. The problem is generated mainly by the fact that there are gravitational accelerations in the three directions of the moving...
