Coordinate Form

Select Mesh→Edit→Coordinates… to open the Coordinate Form

• 

• Select the desired global coordinate system in the Select a coordinate system pop-up menu

• Note that Oblate Spheroidal Coordinates is not yet implemented, and Spherical Coordinates are not fully tested

• If you choose a curvilinear coordinate system, the convention for how local Xi finite element coordinates correspond to global coordinates in a simple geometry is summarized.

• If you choose Prolate Spheroidal coordinates, enter a value for the Focus Position or leave it as the default value of 1.0. Note that all three prolate spheroidal coordinates are dimensionless so the spatial units of the analysis are those of the focus.
