Ansys Discovery – Enclosure Tool, Freezes/lags when certain tasks are performed

[kelvin.k.kong]

UPDATED, I've partially figured out something is wrong with my Full Car model. But I haven't figured out a solution to fix my model. SEE BELOW

Dear Ansys team and fellow users,

On certain functions, in this case using the Enclosure tool. I need to make an enclosure for CFD simulation. Using Solidworks 2024 Assembly document (.SLDASM) However, after inserting the enclosure dismensions in and clicking on the green arrow, the loading circle mouse icon appears, and it doesn't seem to be able to 'unfreeze' itself.  Tried 3 times, without any success. Had to force close Discovery via Task Manager.p>

Other functions, such as using the Interfence tool, it takes a long time for the loading mouse icon to disappear. Other function is using the pull tool to give body panels of my car some width, it's very laggy.
Overall, I find Ansys discovery slow.

Using Ansys 2024 R2 student,
My laptop specs:

13th Gen Intel(R) Core(TM) i7-13850HX
4000 ada 12GB
64GB DDR5 RAM
1TB SSD (~1/3 used)
Windows 11 Pro

Using Discovery application with tonnes of Chrome pages open, and not straining my laptop.

Thanks,

Kelvin

Update:

I installed Ansys 2024 R2 on my other laptop (sufficient hardware to run Ansys), used the same car model as I used previously. The same error occurs.

I also tried with a simple shape, I used a cylinder, and then tried to put an enclosure around it, the same error occurs.

I will try Ansys 2025 R1, and shall update again.

Update 2:

I just tried using Discovery from Ansys 2025 R1 Student on my first laptop (of aforementioned), the same thing still happens!

I was thinking... it might be an issue with my Full Car Model, because using the model from preparation-using-ansys-discovery-lesson-1 , I was able to create a wind tunnel enclosure.

Could non-so-perfect body surfaces be the issues?

Hi 

This can be due to the complexity of the geometry or if the geometry has errors. Please check if the geometry has errors using the check geometry tool. You can use the shrinkwrap tool to reduce the complexity of the geometry.
