+Here the resultant matrix [B]=[A2]*[A1] where [A2] is rotating about the newly oriented z' axis and [A1] is aligning the xyz' axis to the fiber direction. Note that with this ordering the xyz' axis is oriented first then we rotate that oriented system for simulating alternate fiber orientations such as [-45, 45] plies.

   * To better visualize you can hide the geometry in Rhino or set the display to wireframe. This will prevent the object from interfering with the visualization of the simulation.
-The displacement distribution resulting from this static simulation example is displayed below. The maximum displacement is near .5 mm. To load the simulation results later, create a simulation reader block, right-click, select the simulation, and connect it to a visualize block.
+The displacement distribution resulting from this static simulation example is displayed below. The maximum displacement is near 0.07 mm for fibers aligned along the x' (no second rotation). For the 45-degree CW rotation, it should be closer to 0.53 mm. To load the simulation results later, create a simulation reader block, right-click, select the simulation, and connect it to a visualize block.
