1. Shell Element Normals
Jake Blanchard
Spring 2008

2. Element/Area Normals
Areas have normals, with the direction determined by the way the element is defined
Elements meshed on areas will have the same normals
Pressures applied to an element will be positive in the direction of the normal

3. Investigating Normals
Create 2 areas
Show normals (Plot Ctrls/Symbols/Area Direction)
Flip one (Modeling/Move/Reverse Normals/of Areas)
Mesh and apply pressure to all areas
View pressure directions

4. Repeat with Curved Areas
Draw an arc
Extrude around axis from 0 to 30 degrees
Extrude again from 0 to -30 degrees
Apply pressures and look at directions
