ALGOR, Inc., (Pittsburgh) a leading maker of software for mechanical engineers, announces improved design and evaluation capabilities for pressure vessel models, including a new stress linearization utility for use with linear static stress analysis. Now, pressure vessel designers in industries including chemical, petrochemical and power generation can more easily evaluate their designs’ compliance with industry standards such as the ASME Boiler and Pressure Vessel Code (BPVC). PV/Designer provides a modeling wizard that enables engineers to parametrically create pressure vessels. Its new features include full 3-D dynamic viewing with dimension display; a toolbar for quickly defining part, mesh and thickness properties as well as common head types; capabilities for hiding areas of the model using dynamic clipping planes; and parametric on-screen model updating as dimensions and other input fields are modified. Plus, it supports the generation of tapered cylinders and multiple uniform or tapered nozzles intersecting any head or the cylinder.
