How can I resolve assembly recognition issues in ANSYS Workbench 12?

AI Thread Summary
Assembly recognition issues in ANSYS Workbench 12 can arise when importing parts from CATIA in IGS format, leading to some parts not being recognized. Users are advised to check the geometry importing options in Workbench to ensure correct settings. The IGS format can be unreliable, and obtaining a CAD Interface License for CATIA may help resolve these issues. Additionally, when creating parts directly in ANSYS, the software may merge contact surfaces, losing the intended assembly structure. For simpler models, using beam and shell elements in ANSYS Traditional could avoid these geometry complications altogether.

hi
there is an assembly of parts which i want to do static analyse on. i make the parts in cataia and import them as ''igs'' into workbench.problem 1: there are near 7 parts in my assembly which when gets into ansys , ansys doesn't recognize some of them and doesn't show them but it recognize the other parts as solids1,2,3... what can i do if i want the whole assembly in ansys ?
problem 2: instead of importing the whole , after importing some of the parts i tried to make the other parts by its geometry feature but after making the part and pressing generate ansys automatically turns the whole assembly as one parts , i mean it doesn't know the contact sufaces anymore , it automatically merge the whole contact surfaces together . what can i do?> this are the assembly pls take a lokk

check your Geometry importing option in workbench, make sure that u r checked correct importing option. me too had the same problem, sometime it shows more surface in the assembly.
 
IGS format is always a 50/50 gamble. In order to do this correctly you need a CAD Interface License for Catia.
 
In looking at the model, I am assuming that it has no internal parts and therefore, could have been done as a simple beam and shell model in ANSYS Traditional and you would have no problems with geometry since you could have created it all in ANSYS.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
