Dummy question about abaqus
Dummy question about abaqus
(OP)
Hello,
As a newbie, I am trying to learn Abaqus by myself. I made a simple composite cylinder model to mimic a benchmark example. However, I always got a mistake like
***ERROR: 64 elements have fewer than the required number of integration points. The elements are identified in element set ErrElemMissingIntegPoints.
I guess I missed some simple thing somewhere but failed to figure it out myself.
Would anybody give a hand and let me know where I was wrong? (the model is attached)
Thank you in advance.
Sincerely yours
Ming
PS: I am using Abaqus/CAE

RE: Dummy question about abaqus
ou have only one integration point, while 8-noded elements have 4 integrations points.

I was using C3D20R at the beginning and tried C3D20 later. The problem is still there.
What I am trying to mimic is the benchmark problem: 1.1.4 Thick composite cylinder subjected to internal pressure (thickcompcyl_8el.inp), which also uses the C3D20R. The only major change is from UNITS: mm, N to UNITS: m, N.
I really can not figure out where I was wrong. Any comments will be more than helpful.
Sincerely yours
Ming
