Creating a "planar surface"?

[yw5aj]

Dear all,

Sorry about asking such a naive question. I did go through the manual, and did not find the answer, though the question seems really easy.

In Prof. Ateshian's post "Axisymmetric Analysis in FEBio" he mentioned about creating a "planar surface". My question is: can I do that in PreView? And if yes, how?

Thanks!

Hi Shawn,

Under the Create menu select Patch.

Dear Professor Ateshian,

Got it! Thank you so much.

2D patch Boundary Conditions

Dear Professors,

I wander if the fluid mechanics module is developed to allow user to use boundary conditions in a patch. For instance, Prescribed fluid dilation at the curves.
I am having troubles making the patch work. I do the same for the 3D and it works but not for the patch 2D.
And i guess i could also ask. How are the elements of the patch considered?

Thank you!

Hi Roxana,

The fluid mechanics module is only for 3D geometries. If you need to simulate a 2D patch, you need to create a slab (a single layer of 3D elements).

Professor Gerard,

Thank you so much for your response. It is good to know it.
