Hello everybody,

Please could you help me with a problem?, when I reduce the mesh size less than 2mm in a model the computer freezes, I already tried in two computers and the same happens I have research license, I even generated a sphere for only reduce the meshing in the critical area and leave the rest of the model in a larger size (with which it simulates correctly). What can I do to solve it, since there are other users that use smaller mesh size and their computer does not freeze during the simulation?

I assume you mean the minimum cell size. Check the smaller size isn't trying to capture very small edges or faces in the model: that can cause the cell count to increase significantly higher than you're expecting.

Hi rwoolhou,

I am reviewing the model but I do not see many elements in edges or corners, the number of elements 51195

 is and nodes is 232244

What is meshing method?

Please try patch dependent tetra.

Hi kkanade,

Hex Dominant Method

[Keyur Kanade]

Few things to consider. 

Student license has limits. 

Structural Physics: 32K nodes/elements
Fluid physics: 512K cells/nodes

Please check your RAM. Usually 1GB can produce approx 2-3M cells depending on geometry and size functions used. 

Please try to reduce your problem by reducing geometry. 

Also check sizing controls.
