Staad Pro physical modeler - Rectangular tank model and analysis 

Physical modeler in Staad Pro connect edition is very useful while doing analysis and design of structures with a combination of beam elements and plate elements. Physical modeler allow us to make changes in the dimensions of elements easily compared to conventional method until we drop the physical model. Error free mesh generation is ensured along with better control of local axis of plate elements.
in this video a small rectangular tank resting on ground is modeled and analyzed using physical modeler. same concept can be further extended to complicated structures...
