how to change coordinate system in ODB

farzadtb
hello guys ;

i need to know the stress components in a specific direction , so i have to put a local coordinate system that at least the x direction is along the direction i want ( as S11 ) . but when I  create a coordinate system in ODB and move to it , the S11 stresses dont change and I can not see the stress in the desired direction.

I should mention that the ODB file is modifiable and i have disabled the read only tick .

After you've created the coordinate system, go to "Result->Options...",
go to the "Transformation" tab, select "User-specified", select the
appropriate coordinate system, then click "OK".

Regards,
Dave

Coordinate system creation tools are available in the Part, Property, Assembly, Step, Interaction, Load, Mesh, and Optimization modules of Abaqus/CAE (look for the “Create Datum CSYS” icon in the lefthand toolbar).  Coordinate systems used to create part geometries or to define assemblies will not affect the model.  Coordinate systems that are referenced in material orientation definitions, boundary conditions, and loads, for example, WILL affect the model.  See also the documentation for *ORIENTATION and *TRANSFORM.

Please, how do I create a coordinate system and what effect does it have on a model? Your kind responses are appreciated.

Dear Dave Lindeman,

Please, I need help with how to generate a stiffness matrix from displacements plots in Abaqus.

Thanks for your assistance.

You can define a new coordinate system in the viewer for the purpose of
extracting results. It when you select the coordinate system of your
choice, Abaqus will give nodal results and some element results (such as
stress components in tetrahendral elements) in that coordiante system. The
element results such as stresses in beams are given in local coordinate
system, and should not be affected by this - please check it for yourself
as I have not used this in a while. The odb itself will not be affected by
the definition of a coordinate system in the viewer.


In viewer follow the following to create a coordiante system:
Tools >  coordinate systems > create


Kind regards
Ranil

This post has NOT been accepted by the mailing list yet.
I have generated the new coordinate system in the output .odb, but every time I run the analysis, I have to re-establish the coordinate system.  Is there a way to have the output database inherit coordinate systems defined in the model so I don't have to re-establish them every time?

Thanks.
