Thank you for your thoughts, johnhors. Your reply has spurred my interest in the subject of mixing different element types. As I am relatively new to finite element modeling, I've been doing some reading (in these forums, textbooks, journal papers) regarding the matter, and I can't quite seem...
I am modeling contact with irregular geometry and therefore deem it necessary to use modified triangle elements for my 2D axisymmetric analysis, and modified tetrahedrals for my 3D analysis, as per the ABAQUS user manual recommendation. However, I understand that stresses are inaccurately...
I am reading an interesting book entitled <i>Building better products with finite element analysis.</i> In the chapter about boundary conditions, the authors discuss what would be appropriate boundary conditions applied to a simple chair seat where the legs meet the seat, such that the model...
Okay! Thank you very much for you advice. Unfortunately, I still get the same warning message when I do this. Perhaps there is another unrelated problem with my model that is causing this, so I will have to keep testing.
I did create a shell, however for my analysis I would like to use tetrahedral elements, so I require the exterior shell surrounding the block to be solid. I have already tried subtracting the interior block from a larger solid block to create a solid shell, and tying them together, but I...
Hi all,
I wonder, is it possible to use a part to serve as a mold for partitioning another part? For instance, if I create a cube with dimensions 1 x 1 x 1, and another cube with dimensions 0.8 x 0.8 x 0.8, can I use the smaller cube to partition the larger cube such that I end up with a cube...
I received the same 'zero FORCE' warning in a simple model I created of a cylindrical indenter pressing into a square block of foam. This model consisted of two steps: step 1 had a very small pressure (1 unit) applied to the top of the indenter, and step 2 ramped the pressure up to push the...
