*FIXANG

Data format:

An arbitrary number of lines with 3 parameters each, as follows:

NOE IREF IOP
...

Status:

Optional.

Purpose:

To set the orientation (angles) of a node that is connected to one beam element at least.

Restriction:

If the angle you want to fix is too different from the natural angle of the structure, the program may not converge. In that case, you should use *INCDX to fix this angle with a quasi-static calculation

Details :

Parameter	Description
NOE	Node identification number
IREF	Reference coordinates system previously defined by BCREFGLO, BCREFLOC or *BCREFPF
IOP	IOP = 0: Fixang imposed at equilibrium for the section orientation IOP <> 0: Fixang only for post-processing and beam axis

Note

At the node NOE, the vector normal to the beam section is given by the z-axis of the new reference IREF = 0 defines the global reference

Examples :
*BCREFGLO 1 0. 0. -1. -1. 0. 0. 0. 1. 0.

*FIXANG 3 1

The beam section connected to node 3 is along the Y-axis
