Piping analysis

1. Data panel

After analysis, a right panel can be opened by clicking on the top button (1). It presents the selected results :

Shortcut to open the data panel = F2.

2. Results

Click on the RUN button :

After a few seconds, the results of the analysis are shown. This panel will appear :

Select a case and the type of results :

• Displacements
• Forces and moments
• Reactions
• Stresses

2.1 Load cases

The combobox shows all calculated load cases :

The loadings can be defined here.

The Modes are generated if the Extract modes is checked in the Model options screen :

Click here to have more information about the model options.

A special load case “Fatigue” is added at the bottom of the combobox for Class 1 piping codes (Code Aster solver only). It allows to visualize the results of the detailed fatigue analysis : elastic shakedown (Eq. 10), usage factor, thermal ratchet, etc.

2.2 Displacements

1. Select the Displacement button
2. Open the right Data panel
3. Select a node
4. The results are highlighted

Shortcut to open the data panel = F2.

The Data panel shows the global displacements for each node.

Property	Description	Unit Metric	Unit USA
Node name	Text or number	-	-
DX	X global displacement	mm	in
DY	Y global displacement	mm	in
DZ	Z global displacement	mm	in
RX	X global rotation	Rad	Rad
RY	Y global rotation	Rad	Rad
RZ	Z global rotation	Rad	Rad
D	global absolute displacement	mm	in
R	global absolute rotation	Rad	Rad

The Selection mode is automatically set to POINT.

You can amplify the displacement by changing the factor cursor.

INTERACTIVITY :

1. Click on a Column header to sort the results in ascending or descending order
2. Select a row
3. The node is highlighted

TIP : you can copy the data by CTRL+C and paste in other software.

2.3 Forces and moments

1. Select the Force button
2. Click on a column of the Data panel to sort the data
3. Select a row
4. The corresponding element is highlighted

Shortcut to open the data panel = F2.

The Data panel shows the forces and moments for the 2 extremities of each element.

Property	Description	Unit Metric	Unit USA
Element	Type	-	-
Node	Node name of the extremity	-	-
F1	Force 1	N	lb
F2	Force 2	N	lb
N	Normal force	N	lb
M1	Moment 1	N.m	lb.ft
M2	Moment 2	N.m	lb.ft
T	Torsion	N.m	lb.ft
F	Absolute force	N	lb
M	Absolute moment	N.m	lb.ft

The Selection mode is automatically set to ELEMENT.

2.4 Reactions

1. Select the Reaction button
2. Select a row on the data panel
3. The corresponding restraint is highlighted

Or select directly a restraint to highlight the corresponding row.

Shortcut to open the data panel = F2.

The Data panel shows the forces and moments (reactions) for each node.

Property	Description	Unit Metric	Unit USA
Node	Node name	-	-
FX	X component of the reaction force	N	lb
FY	Y component of the reaction force	N	lb
FZ	Z component of the reaction force	N	lb
MX	X component of the reaction moment	N.m	lb.ft
MY	Y component of the reaction moment	N.m	lb.ft
MZ	Z component of the reaction moment	N.m	lb.ft
F	Absolute reaction force	N	lb
M	Absolute reaction moment	N.m	lb.ft

The forces are represented by a simple arrow.

The moments are represented by a double arrow.

The Selection mode is automatically set to RESTRAINT.

2.5 Stresses

1. Select the Stress button
2. Select the result type
3. Click on a column of the Data panel to sort the desired data
4. Select a row
5. The corresponding element is highlighted

The results are code dependent. The third column shows the stress ratio, defined as the calculated stress divided by the allowable stress.

The stresses are shown at each extremity of the elements. The maximum stresses of both extremities may be displayed instead by checking “Show max element stress” :

The Selection mode is automatically set to ELEMENT.
