I am going to construct a tet element for my model. Let you know if it works well. Jay

Hi lanavi017, How do you make them work together? Thanks a lot for sharing! Jay

What element type do you use ? I used to use CPE4. Which did you choose ?

Hi Andre, I encounter the same problem before. That's some kind of numerical oscillation problem. The problem could be your mesh size irregularity. So do finer the mesh and test. Jay stungj@gmail.com

Dear all, I am interested in the coding standard of writing a subroutine as well. Thanks. Jay

Did you check the output geometry? There should be some subroutines to remesh.

Greg, Thanks a lot. I will try the function of coincident nodes in abaqus. Cheers, Jay

MNS747 I have the same problem of extract the nodes. How do you make it ? Thanks

Thanks. In order to do elastic dislocation constraint, I need a pair of node on each contacting location. Those two nodes in each pair are of same position but with different movement so that a slip is simulated. I have have written a small c++ script to pick each pair but I wonder if there...

After setting up the model in CAE, involving drawing geometry and assigning material, is there any subroutine for me to extract the location of some designated nodes ? We need to add some constraints in those nodes. The extract nodes are those contacting nodes of two instances. Thanks

I think "Tie function" is to share the same displacement amongst points. The unrealistic stress field may be attributed to the mesh size and your boundary conditions.

Thanks Rob. If I want to do some iterations like 1. draw a geometric object in solidwork 2. import to abaqus and mesh 3. export the the deformed geometric object 4. can i automatically mesh the deformed object again in abaqus ? 5. deform it.. 6...repeat step 4 and 5 or i need some other...

There is problem if the nodes are very dense or your path is not that straight. 1001 or <1000 could be resulted from some mistakenly selected nodes. So you should select them carefully or you find another logical ways to isolate them out, like making them to be a boundary of a section.

Thanks Timusop. Could I design the mesh with the CAD package ? I also heard about Rhino for model design. Is it good ? Many thanks, Jay

Dear All, I am going to draw a 3-D model to be run in Abaqus. I would like to know how I can do that. I find it is a little bit cumplicated to design the 3-D structure with certain curvatures in CAE. Could anyone tell any assisting softwares or approaches of designing the 3-D geometry in a...
