How to model infinite part for axisymmetric elements in Abaqus?
How to model infinite part for axisymmetric elements in Abaqus?
(OP)
Hi, I am trying to model an infinite boundary for 2D soil media with different layers in Abaqus.
I want to add an infinite part to the axisymmetric elements. I tried that with defining acoustic elements (ACAX4) and then convert into infinite elements (CINPE4) in .inp file. But it was done by a mixture of 2D and axisymmetric elements. Is this ok or can anyone recommend me a method?
Also, how to assign different material properties to different layers after obtaining the infinite elements (it becomes an orphan mesh part).
Thanks

Hello
I have the same problem as you mentioned. Please help me know if you found the solution of this problem.
Thank you

I used the same method I explained in the problem and convert the ACAX4 elements into CINAX4 in .inp file.
Is that the answer you want?
Thanks,

Thank you for your help.
I am trying to work with orphan mesh, but I have some problems. Do you have any references about orphan mesh and how it works?
Best regards

thanks a lot. I saw these videos and they are great. I have problem with assign different material properties to different layers after obtaining the infinite elements with orphan mesh.
