Node Support Orientation > New/Modify
Defining or modification of node support orientations.
Setting | Description |
---|---|
From / To / Step | Series of nodes where orientation angles shall be defined or modified. |
Beta | Angle between the local y axis and the default y axis as defined by definition of Alpha1 and Alpha2 |
Alpha1 | Angle between the local x axis and the horizontal (global X-Z) plane |
Alpha2 | Angle between the global X axis and the projection of the local x axis to the horizontal plane (X-Z plane) |
Default axis y'L in the vertical plane through the element axis (parallel to axisYG)
Note: The local node coordinate system is built by rotating the default global vector system. At first the x vector is rotated by Alpha2 around the global Y axis (definition range 0° to 360°. Then the vector is rotated by Alpha1 out of the horizontal plane (definition range -90° to 90°). Finally the vectors y and z are rotated around the local x axis.
