importing catia file to ansys 1

[isb07]

greetings everyone

i was trying to import Catia V5 file to ansys (V13)

every time i import i get Following error

"Connection for catia v5 directory structure is not set.
unable to find connection directory"

If i try to import it by iges file than only lines are transferred not as solid.

sometimes its not transferred completely

regards

Try importing as a parasolid or step if you can, iges is a very old standard (in fact, not even a 'standard' as such) and is fairly useless as a solid model. You need to set up the connection for catia (as the message implies) which you would normally do when installing the software (ANSYS) from scratch. You can try setting this up by re-installing just the catia component from the ANSYS DVD.

Thanks Drej

it worked when i installed the connection for Catia V5...

Simple drawings are imported But its not accepting for some of the drawing

It gives following error

"No areas selected to display. The APLO command is ignored"

also When i try to import as stp file, i get following error

"Because key point merging has not been performed, automatic volume creation is suppressed."

Regards

Hmmmm. Make sure when you export the geometry from CATIA that you select export of *all* geometry (keypoints, lines, areas, volumes). You could however have a case of "bad" geometry from CATIA and may need to fix this within CATIA before you export. A tool like CADfix is ideal to fix/heal geometry if you have it. Try also - if you can - importing the geometry into another package (ABAQUS etc.) to see if it imports correctly.

thanx drej for your support

Now m using Ansys workbench and its working fine...

earlier i was using Mechanical ADPL (Ansys)

Does it make any difference to use workbench as i found Workbench to be more user friendly..

 

[Drej]

It depends. It depends on the type of models you deal with and run, how you like to work as an analyst, and ultimately what you're most comfortable with. Mechanical has more functionality and is just a different user experience compared to WB. WB working ethos is geometry based, and if you have a very large model with lots of contact etc it's arguably easier to set up in WB. Personally, I prefer Mechanical because I like to write everything in APDL, and if given the preference I would always use this because I feel I have more control over my model. Plus it's more fun

Under the bonnet there are some subtle differences between the two - for example, WB and Mechanical have different meshers (or at least used to), and the consensus is that the "better" mesher (i.e. more robust, better general mesh quality, etc.) resides within WB, but I'm used to the Mechanical mesher and it does everything I need. It depends what you're used to working with but personally I prefer the Mechanical interface for the work that I do.
