FluidFlow allows you to model two types of relief devices, relief valves, and bursting discs. Users have the option of defining the size of the valve or disc or alternatively, allowing the software to automatically size the components for you based on the system operating conditions. Users can choose from the sizing methodology applied in API (American Petroleum Institute) RP520 Part 1 and ISO 4126-1.
