Patran Results
(OP)
Hello all,
I am starting to learn Nastran / Patran and I have som doubts.
1. If I have one quad next to another one, a one of them have the coord.system parallel to the global, the other quad is reverse. There is impact inn my results??
2. Which is the difference between check ths stress plot with Coodinate Transformation: AS IS / CID / Projected CID / Global / Default / Material / Element IJK?
Someboy have any document which talk about axis system in nastran/patran and which is it's influence?
Thanks on advance

RE: Patran Results
It's a very bad way of modeling - get your normals in sync to minimize problems.
COORD systems are relevant when dealing with the following:
1. non isotropic materials.
2. checking results in different coord systems.

I see...but according to this, Which Axis are used for NASTRAN solution? Global Axis, Element Axis...
RE: Patran Results
if you define loads/constraints and so forth in a certain coord system, then that coord system is created in the BF file.
there is a difference between the result processing coord systems, and the solution coord systems.
