FEM using INVENTOR-Want to determine the number of Elements in the FE mesh

Hello All,

 

I am learning how to use Inventor for doing FEM simulations. I just wanted to know if there is a way i can determine the number of elements in the FE model after the mesh generation process?

 

Thanks in advance for the help.

 

sincerely,

James

Thanks for the ans. I had already seen it. I am just wondering whether you can also vary the element type in inventor? We seem to have tri elements. Can one change it to QUAD?

 

Thanks!

In case you are interested, the number of nodes is probably of more use. Since the degrees of freedom is equal to the number of nodes x 3 for solids or x 6 for shells minus the number of degrees of freedom you fix with boundary conditions per node. The degrees of freedom are equal to the number of equations that must be solved for a direct solver and will give you a good guide as to how long your simulation will take.

No, only tetrahedral elements in Inventor. You might want to look into Autodesk Simulation (Algor) if you need more element types.

Hi,

 

I have another problem or question. I wanted a benchmark that i could use to test the accuracy of the FEM solvers in Inventor and ANSYS STRUCTURAL. I am interested getting data on the Fichera Problem. Any ida how i can get this?

 

Thanks!

Not sure on Inventor's FEA, but with the Mechanical Simuation (formerly Algor) there are verification models on the Autodesk website. You will need to go to the Product Support section for Mechanical Simulation. You should be able to navigate to it from the Support icon at the top of this user forum.

Check out the following link. It compares Inventor Simulation and Autodesk Simulation 2012 to NAFEMS benchmarks. http://images.autodesk.com/adsk/files/autodesk_simulation_tools_NAFEMS_white_paper_en.pdf
