Planar Mapping

You use the planar mapping option to project a common 0º reference to a group of faces or surface bodies.

To use the planar mapping option, in the Simulation study tree, right-click a shell icon and select Edit Definition. In the PropertyManager, under Type, select Composite and under Composite Options, select Planar Mapping.

You can use one of the three orthogonal XY, YZ, or XZ planes for defining the projection direction. For example, the image shows the roof of a car frame model using the XZ plane for planar mapping. In general, the projection plane must be parallel to the shell face.

You can also use a reference face or edge to define the projection direction. For example, in the boat tray model, you can use one of the parallel shell faces as Selected Reference to project the 0º reference to the other faces.

When to Use the Planar Mapping Option

You use the Planar Mapping option to define a common 0° ply angle reference for a group of planar shell faces or if you encounter problems with the default Surface Mapping option.

Inappropriate Ply Orientation

The image shows a face created using the surface fill operation. The surface mapping technique that uses the UV coordinates shows curved stripes on the shell. You can use the planar mapping technique by selecting the XY plane and projecting the desired ply orientation.

Inconsistent Orientation Across Faces

The image shows consistent ply orientation across multiple faces with the planar mapping option. The surface mapping creates inconsistent orientation for a 45º ply angle across the faces.
