In the 1D element list, the green elements have a correct definition, the orange elements have a warning, and the red ones have a bad definition.

A warning will occur if one or two nodes of a 1D element belong to one or more of the following entities:

•An accelerometer
•Another 1D element having the same type and the same property
•An added mass

An Error will occur if one or two nodes of a 1D element belong to one or more of the following entities:

•A skew frame
•A sensor
•A time history
•An interface (except interfaces type 2)
•A gravity
•An initial velocity

Note:        The third beam nodes are not taken into account for the check.

Two columns show the warning and the error for all 1D element types:

•The column, Loose, shows the number of "loose nodes": 0, 1, or 2.
•The column, Connec., shows the number of 1D element nodes linked to elements having the same type and the same property.

 

To correct the elements with an automatic loop:

1.Click automaticGeneral-24 to activate the automatic correction. The element is displayed in blue in the graphic window and messages are printed in the message window to explain why the element has an error or warning.
2.Click the right mouse button in the context menu and select one of the following:
•See loose nodes if the element has an error.
•See Nodes, which might not be properly connected if the element has a warning.
3.Modify the element.

or

Merge the node(s) to reconnect the element.

or

Add the node(s) in a rigid body.

4.Click automaticGeneral-24 to stop the automatic correction.
