Number Problem Size Limit

      Hey, 


       


      So I'm a student and under normal circumstances have access to a fully licensed version of the software at university. However, these aren't normal circumstances and I'm having to use the student version of Ansys from home. My issue is the size limit, I've already halved the model and this has allowed me to put a 20mm mesh on the model. I would like to get a more accurate mesh on the model. I've attached the model and any help would be appreciated.

      Can you further reduce the domain size? Alternatively, do you have VPN access to the Uni machines?

      I would usually use external software to create and then import the geometry like CREO/Solidworks etc. However, they are also not available to me. So I'm wrestling with unfamiliar commands in design modeller. How would I go about reducing the domain?


      And unfortunately no, I don't have VPN access, that would be a reasonable solution but alas, no.

      please try spaceclaim. it is very easy to use. 


      you would find many videos on splaceclaim on youtube.

      @KKanade,


       


      Without meaning to sound negative that's a lie, SpaceClaim is awful. I have a perfectly fine model attached made in design modeller, what advantage will I gain from remaking it in the god awful SpaceClaim? Also, the first reply suggested reducing the Domain, I have replied asking how would I go about reducing the domain? So how would I go about reducing the domain? I'd prefer if the answer didn't involve remaking the model in SpaceClaim. 


      I can only apologise for the tone of this response but that wasn't helpful. I do appreciate you taking the time to help and any help would be appreciated.


      Thanks

      In DM you can use planes and surfaces to slice the model. Depending on the shape (I still am not allowed to download the image) you may be able to model 1/6 of the domain or similar.

      There's a boss at the end of the geometry preventing any further lines of symmetry. It's for a six sigma and optimisation coursework. I've attached some images in the hope that you will be able to at least have a better idea of the geometry. Again I appreciate the help, otherwise, the report will be written without a model to work on which sounds horrendous to me.

      While posting question, please make sure that you insert images and describe the issue correctly. As ANSYS Staff, we can not download attachments. 


      Without looking at images and not having information about problem, it is difficult to advice. 


      As you have posted images now, it is clear that you can not reduce the geometry domain further. 


      Now to reduce mesh size, the best potion is to use hex mesh. Again generating full hex mesh in this geometry would be difficult. But you can slice the model and get hex mesh in part of the model and rest can be meshed with tet mesh. 


      For slicing model in SpaceClaim look at 



      If you still want to use DM, you can have a look at

      I'll bear that in mind in future, thanks for your help, I'll see how it goes.
