There are a few options to export, however it depends on what mesh type you are using and what you are trying to export, i.e., exporting results, the geometry, etc.
Let me know.
ok, for example if i have one CAD file imported in Moldflow & wants make some changes in the structure, is possible export the geometry (Part) and then import again to moldflow??? wich extension is proper?? if i want open the file in Catia or NX.
Although Moldflow can export certain formats, many of which are usable in external CAD programs (IGS, Patran, etc.), Moldflow is not a CAD modeling tool and thus changes should be made in CAD modeling programs with the new model imported into Moldflow. Ideally, you would want to make structual changes in your CAD package, then reimport any changed geometry into Moldflow if you want to reanalyze it. You can use Moldflow to make structural changes, however there are limitations in doing so. I believe Catia can supprt IGES files which Moldflow can export, but to be 100% you'll want to determine which file types of sutiable for Catia and we let you know if we support it.
