<Pipe>
This pipe element is the "StressGroup" in PSI - it is stored as a PIPE element
<FullName>/XP36-GROUP</FullName>
The name of the stress-group
<Ref>=2013286672/1995</Ref>
The AVEVA E3D™ reference of the stress-group - this is used, on the return for identifying the stress-group
<Branch>
The branch however is a "real" AVEVA E3D™ branch included in the Stress-Group
<Branchname>/XP36A</Branchname>
The name of the AVEVA E3D™ branch
<Temperature>
CAESAR II allows up to 10 temperatures at each node, AVEVA E3D™ stores one at a branch level, PSI allows you to specify extra temperatures, but not varying over the model.
<Temperature1>330</Temperature1>
All the temperature elements use the units defined in the <TemperatureUnits> element
<Temperature2>-100000</Temperature2>
-10000 is used by AVEVA E3D™ for unset values
<Temperature3>-100000</Temperature3>
<Temperature4>-100000</Temperature4>
<Temperature5>-100000</Temperature5>
<Temperature6>-100000</Temperature6>
<Temperature7>-100000</Temperature7>
<Temperature8>-100000</Temperature8>
<Temperature9>-100000</Temperature9>
</Temperature>
<Pressure>
CAESAR II allows up to 10 pressures at each node, AVEVA E3D™ stores one at a branch level, PSI allows you to specify extra pressures, but not varying over the model
<Pressure1>17</Pressure1>
All the temperature elements use the units defined in the <TemperatureUnits> element
<Pressure2>0</Pressure2>
-10000 is used by AVEVA E3D™ for unset values
<Pressure3>0</Pressure3>
<Pressure4>0</Pressure4>
<Pressure5>0</Pressure5>
<Pressure6>0</Pressure6>
<Pressure7>0</Pressure7>
<Pressure8>0</Pressure8>
<Pressure9>0</Pressure9>
</Pressure>
<MaterialNumber>102</MaterialNumber>
The material number is an integer, and is passed straight through to the .CII file.
<InsulationDensity>100</InsulationDensity>
<FluidDensity>1000</FluidDensity>
<Node>
<NodeNumber>-1</NodeNumber>
If the node-number is -1, then the node should not be represented in the output file.
<Endpoint>1</Endpoint>
The Endpoint is broadly equivalent to the AVEVA E3D™ ppoint of the node (except that endpoints 1 and 2 are the parrive and pleave, rather than ppoints 1 and 2.
For some component types we only consider some of the endpoints:
we need the node at endpoint 0 for a bend
node 0 of a tee is needed for connecting branches
when we reach endpoint 2 of a reducer we have both sets of diameters available
and there is some logic involved in identifying rigid components. What I currently use is:
if((componentType=="RIGID") ||
((endpoint==2) &&
((componentType=="GASK")||
(componentType=="FLAN"))||
(((endpoint==2)||(endpoint==0)) &&
(componentType=="VALV")||
(componentType=="FILT")||
(componentType=="INST")||
(componentType=="PCOM")||
(componentType=="TRAP"))))
{
data.rigidData().m_enabled=true;
the (componentType=="RIGID") case does not, I think occur in any XML files written by the released PSI - but did in some pre-release versions.
<Rigid>1</Rigid>
<ComponentType>BRAN</ComponentType>
The component type is the AVEVA E3D™ element type
<Weight>0</Weight>
The weight is in <WeightUnits>. For a rigid block made up of several AVEVA E3D™ components the PML will assemble, and if necessary distribute the total weight, and will assign the combined weight to suitable nodes in the XML file.
<ComponentRefNo>=2013286676/3060</ComponentRefNo>
The AVEVA E3D™ element reference - primarily used for identifying components whn data is being translated back from the stressing package.
<OutsideDiameter>88.9000015258789</OutsideDiameter>
In <BoreUnits>
<WallThickness>3.17</WallThickness>
In <WallThicknessUnits>
<CorrosionAllowance>1</CorrosionAllowance>
In <CorrosionAllowanceUnits>
<InsulationThickness>150</InsulationThickness>
In <BoreUnits>
<Position>6867 3700 1490</Position>
In <DistanceUnits> with respect to the world
<BendRadius>0</BendRadius>
In <DistanceUnits> - set to zero for "not a bend"
<SIF>0</SIF>
This element is misnamed - it does not contain a SIF value, but may contain a tee-type code as used in CAESAR II (this ends up in the SIF & TEES table in the .cii file) - we may need to consider changes in this area, depending on how other stressing packages handle tees.
