Solve a range of problems with a diverse set of scenarios and effects

Loss of containment scenarios from pressure vessels, storage tanks, pipework and pipelines are easy to create. Phast automatically determines the type and extent of the consequence effects.

Within a matter of seconds, you can have the answer to the problem you are trying to solve.

Also supported are a range of "standalone" models, user-defined sources and adjustable parameters, giving you full control for specifying loss of containment scenarios.
