X.B.4 Modification of coordinate systems

One gives here additional information on the modification of coordinate systems with Result method “modifyRefCoordSys”. When developing the various transformations possible with this function, one tried to keep as much as possible, the correspondence with Patran (Patran 90) transformations. Sometimes, this process has been partially done by trials and guesses until an agreement was found.

In the rest of the section, one gives the information allowing the user to determine exactly the operations that are performed on finite element entities and coordinate systems to defined the transformed coordinate system. One makes the distinction between local, global and projected coordinate systems.

  X.B.4.1 Local coordinate systems
  X.B.4.2 Global coordinate systems
  X.B.4.3 Projected coordinate systems
  X.B.4.4 Local coordinate systems of CQUAD4 elements
  X.B.4.5 Local coordinate systems of 3D elements
