Problem with CAD Integration: UG NX4

[cbrn]

Hi,
the company is shifting from Unigraphics NX2 to NX4 and so the CAD Integration plugins of ANSYS v.11 must be shifted as well.
We are running into a problem:
the plugin / converter seems to install correctly, in fact in Ansys Classical we are able to open any NX4 model. But in Workbench, the plugin doesn't want to initialize properly because it says:
"Error Handling Failed: Could not open Unigraphics main defaults file"
But UG on its own starts with no problem and finds the correct LoadOptions, so what?

Thanks in advance to anybody who can throw some light on that!

Regards

Hi,
problem solved.
It's unlikely that someone else will have the same problem, however here is why it happens:

when two versions of UG NX, say NX2 and NX4, are running "in parallel", the "PATH" variable contains both the path of NX2 and the one of NX4. Ansys WB 11 with the NX4 reader won't handle it correctly IF the path to NX4 is written AFTER the path to NX2, because the first it founds is formally correct but inconsistent with the version. It is sufficient to write the path to the latest version before the one(s) to the older version(s). In addition, the same "reordening" must be done in the "ds_custom_dirs.dat" file.

To further complicate things, if as in our case you are also running both Ansys 11 and 10 (Ansys 10 can only handle NX2 plugin/reader) you have to "reorder" each time and so you'd better play with ".bat" launching files.
