Contents |
SID |
Set identification number. (Integer > 0) |
GSID |
Grid point set identification number. Default = all grids in the model (blank or Integer > 0) |
VT |
Initial velocity along the axis. (Real) |
VR |
Initial velocity about the axis. (Real) |
GA/ XA, YA, ZA |
Axis origin. These fields define the origin of the axis. The point may be defined by entering a grid ID in the GA field or by entering X, Y, and Z coordinates in the XA, YA, and ZA fields; these coordinates will be in the basic coordinate system. Default is the origin of the basic system (Real in all three fields or Integer in first field) |
GB/ XB, YB, ZB |
Direction of vector for axis definition. These fields define a point. The vector goes from the anchor point to this point. The point may be defined by entering a grid ID in the GB field or by entering X, Y, and Z coordinates in the XB, YB, and ZB fields; these coordinates will be in the basic coordinate system. No default (Real in all three fields or Integer in first field) |
| 1. | Explicit analysis initial condition sets must be selected with the Subcase Information command IC = SID. It can only be selected in explicit subcases which are defined by an ANALYSIS = NLGEOM subcase entry. |
| 2. | TICA is primarily used for simulating the uniform rotation of a structure about an axis by defining VR and an axis. A helical (or spiral) shaped motion can also be achieved by defining VR, VT and an axis. |
| 3. | This card is represented as a loadcollector in HyperMesh. |
