Downgrade .odb version from 6.14 to 6.10/6.12?

[ShadowWarrior]

I am using an in-house code to visualize results from .odb file but it only supports version 6.10 to 6.14 odb file. Is there an utility or tool to downgrade the version of .odb file?

 

[ShadowWarrior]

Is there anyone that can help?

Do you have to use the in house visualization code? Can you not use some other tool?

re-run the analysis with an older installation?

 

[ShadowWarrior]

It will take couple months to re-run the analyses with an older ABAQUS version.

There is capability to build a new odb from an existing odb. It's described in the scripting manual, with an example. These guys made a plug in for doing it:

However, I don't know if it's possible to build a new odb in the format of a prior release. I'd contact your local simulia rep, they should tell you immediately.

Is it a big task to update the in house code?

 

[ShadowWarrior]

Yes, its quite a large code base so updating it is not an option.

Another option would be to convert the odb to vtk format and use paraview to post-process.

I found a script that does convert the odb file to vtk, but I am encountering an error because my simulation was performed in double precision (it works fine with single precision data).
The error is occuring at line 183 of the odb2vtk.py file -
OdbError: Data is double precision. Use dataDouble()


Anybody can suggest where I should modify the python code? -
