Create nodes

There are 3 possibilities of creation :

  • Creation of the FIRST node
  • Creation of a GLOBAL node
  • Creation of a RELATIVE node

1. First node

The first node panel is called when a first element needs a starting point. Example for a pipe :

Image

Set the GLOBAL X, Y, Z coordinates and a name.

See Global node just below :

2. Global node

If the selection is EMPTY, click on the Add node button to create a new global node :

Image

ATTENTION, the current specification is important (Ex : 6” Sch 40) for the default node connection.

Fill the GLOBAL X, Y, Z coordinates and a name (1).

Property Description Unit Metric Unit USA
X X global coordinate m ft
Y Y global coordinate m ft
Z Z global coordinate m ft
Name Text or number - -
To know the UNIT of the value, just let the mouse over the cell. 

If Name is blank, the new node will receive an automatic name based on the Node settings.

All new node follow the current specification node connection properties (2) :

Property Description Unit Metric Unit USA
Mismatch Mismatch for welded joints mm in
Fillet length Length of fillet weld Cx mm in
TMax for Class 1 transition within 1:3 slope envelope mm in

The Joint can be :

  • None
  • Butt weld - flush
  • Butt weld - as welded
  • Fillet weld
  • Full fillet weld
  • Threaded
  • Brazed

In this example, the values correspond to current specification preset :

Click the Create button to create the first node of the model.

3. Relative node

If a node is selected, you can create a new node relative to it in Global directions :

Image

  1. Select the current section/material in the specification box.
  2. Select a node.
  3. Define the DX, DY, DZ, name of the new node.
  4. Define the node properties

Property Description Unit Metric Unit USA
DX Relative distance from the selected node in X global direction m ft
DY Relative distance from the selected node in Y global direction m ft
DZ Relative distance from the selected node in Z global direction m ft
Name Text or number - -

If Name is blank, the new node will receive an automatic name based on the Node settings.

  • Butt weld - as welded
  • Fillet weld

  • Brazed

4. Creation of a local coordinate system

You can define a new local coordinate system on selected node (5) :

Image

Just define the new X axis vector (Xx, Xy, Xz) in global coordinates and the new Z axis vector (Zx, Zy, Zz). The Y axis will be automatically defined by the right-hand rule.

Example :

Image

Click on the Create button to add a new local coordinate system to the model.

You can later modify or remove this object by selecting this node and click on Modify/Remove buttons.

You can Undo this command.

Another example with an off-axis piping :

The default global axis are :

To define the Local X-axis tangent to the pipe, change the vectors like this :

5. Creation of a lumped mass

You can define a lumped mass on selected node (6) :

Image

Property Unit Metric Unit USA
Mass ton kips

Click on the Create button to add a new lumped mass to the node.

You can later modify or remove this object by selecting this node and click on Modify/Remove buttons.

You can Undo this command.


6. Modify a node

Change the Selection mode to POINT and select a node :

You can change the node properties.

Click on the Modify button to change the selected node.

You can Undo this command.
