In Mechanical models, the limit is 32,000 nodes or elements

In CFD models, the limit is 512,000 nodes or elements

In Geometry, the limit is 50 bodies and 300 faces.

no way to increase those limits?
I mean what if someone wants his model to be with a lil higher nodes and elements?

there is no way to increase limits. 

you may want to decrease your problem size. you may need to use 2d instead of 3d etc. 

if you really want to increase limits, you may want to talk with your prof and corresponding account manager. 

please mark this as 'is solution' to help others on forum.

One way to increase the node density is to take advantage of symmetry. If your geometry and loads are symmetric, then you cut your model in half and apply a symmetry boundary condition.

If your model is not symmetric, use a coarse mesh where there is a low rate-of-change in the solution and use a fine mesh where there is a high rate-of-change in the solution. In that way you put the nodes where the "action" is.

is that the only way?...cuz i saw the model in one of the tutorial on youtube and did exactly the same whilst the model shown on youtube ran properly...but its failing in my case owing to the error captured above

also it would be great if anyone can tell me the best place to learn more about meshing n stuff on ansys...(basic to advanced), it will be really appreciated, thanks in advance.

Hi omi123,

Regarding your latest question, I would recommend to create a new thread in Tutorials, Articles and Textbooks  category.

Thanks,

Win

Omi,

Your academic institution might have purchased an unlimited Research license. Ask them if they have.  If you are employed, your business might purchase an unlimited Commercial license.  I am lucky to have access to an unlimited Commercial license.

If you only have access to the free Student license, then you have to operate within the limits of that license. I just helped someone whose model ran in an unlimited license and reduced the node count to the point where it would run in the Student license limits.

I can help you too if you describe in detail what you are trying to do.

Regards,
Peter
