13.2.3. FiberSIM-to-ANSYS Translation Details13.2.1. Understanding the FiberSIM XML File
The FiberSIM .xml file contains detailed orientation data for each layer in the laminate. Each FiberSIM
ply is represented as a triangular facet mesh with node data (X,Y, Z) followed by facet connectivity
data (node1, node2, node3, warp, weft). The data is necessary in ANSYS, where the fiber orientation is
required over the entire layer surface. You map the FiberSIM .xml data to existing ANSYS elements
using the FiberSIM orientation data. The warp and weft are the angles in radians from side node 1 -
node 2 of the facet of the two fiber orientations. Hence, warp is used to define the layer orientation.
Weft is not used.
For sections incorporating FiberSIM data, the .xml file containing the FiberSIM data must exist in its
original format. ANSYS cannot use the data if you have altered the file in any way (for example, by
opening the file in an XML editor, making changes, and then saving it again).
ANSYS accepts long ply names (up to 72 characters) if they are present in the FiberSIM file.
In this example, the sample.xml FiberSIM file demonstrat es an extremely simple model of a square
with five layers, including one partially dropped layer:
