Defining an anchor plane

You can define an anchor plane to indicate where part deflection is measured from.

At the beginning of a Warp analysis, the analysed part is automatically constrained to a plane where part deflection is measured from. This plane is defined as the anchor plane. During post processing, the warpage deflection results can be displayed relative to any arbitrary anchor plane.

1. Under the Warp results in the Study Tasks pane, select a Warpage result.
2. Ensure the model is at a suitable rotation for setting three reference points to define an anchor plane. The three points must be on the same Z axis.
3. Click (Results tab > Results panel > Warpage Constraints). The Warp Constraints dialog appears.
4. Click the model or enter the X, Y and Z coordinates to specify the three points on your model that define the anchor plane. If you choose to enter the coordinates, click Add to register each point.
   • The first point defined is the anchor point. This point is constrained in all directions (X, Y, Z).
   • The second point defined is constrained to move only in the X direction.
   • The third point defined is constrained to move in both the (X and Y) direction.
5. Specify the nominal maximum deflection value to be used for the warpage assessment.
   Note: The default nominal maximal deflection is equal to approximately 50% of the average thickness.
6. Click Apply if you have entered the reference point values manually, to update the warpage values for this plane.

Note: You should carefully consider the position of the anchor plane when viewing warpage results. In areas that are distant from the anchor plane, the calculated deflections may comprise an in-plane shrinkage component as well as out-of-plane shrinkage.

Tip: You can drag the anchor plane points about the part to update the anchor plane in the warpage result display.

Tip: Click and hold down the Shift key while dragging your mouse cursor either up or down to increase or decrease the size of the anchor icons ().
