Introduction

Welcome to DotNetPWS - the .NET SDK for Phast Web Services. The .NET SDK provides an easy and efficient way of consuming the Phast Cloud APIs in your .NET based solutions.

What is Phast?

Phast is the world's most comprehensive process hazard analysis software which models the progress of a potential incident from the initial release to far-field dispersion including modelling of pool spreading and evaporation and resulting flammable and toxic effects. In Phast Web Services we have taken the same state of the art consequence modelling calculations and made them available as web services so you can use them in your own applications.

Concepts

Phast Web Services have been designed to use "entities" that are easy to grasp conceptually. So you work with physical objects like a vessel or a pipe and associated data objects like leaks, pipe ruptures and weathers. These are used when calling a vessel leak or pipe breach calculation for example.

Getting started

Full documentation and samples can be found here.

Example

The following example shows how to instantiate, populate and run a vessel leak calculation.

var vesselLeakCalculation = new VesselLeakCalculation();

vesselLeakCalculation.Vessel.Diameter = 8.0;
vesselLeakCalculation.Vessel.Length = 20.0;
vesselLeakCalculation.Vessel.Shape = VesselShape.HorizontalCylinder;
vesselLeakCalculation.Vessel.Material = new Material
{
    ComponentCount = 1,
    Components = new List<MaterialComponent>
        {
            new MaterialComponent
            {
                MoleFraction = 1.0,
                Name = Material
            }
        },
    PropertyTemplate = PropertyTemplate.PhastMC
};

vesselLeakCalculation.Vessel.State.Temperature = Temperature;
vesselLeakCalculation.Vessel.State.Pressure = Pressure;
vesselLeakCalculation.Vessel.State.FlashFlag = FluidSpec.TP;

vesselLeakCalculation.Vessel.VesselConditions = VesselConditions;
vesselLeakCalculation.Vessel.LiquidFillFractionByVolume = LiquidFillFraction;

vesselLeakCalculation.Leak.HoleDiameter = HoleDiameter;
vesselLeakCalculation.Leak.TimeVaryingOption = TimeVaryingOption.TimeVaryingRate;

var calculationResponse = vesselLeakCalculation.Run();
