Abaqus contact controls 2
(OP)
Thanks for help about contact controls.
Now I ask you a question about dumping coefficent.
You said me to obtain the solution in problem involving contact with difficult convergency could be subdivide the analysis in multiple step decrasing dumping coefficent.
You said me the factor in step_1 must be (for example) FACTOR=1 e-06 and in the second one FACTOR=1 e-05.
-Have you make a mistake (FACTOR=1 e-05 is bigger then FACTOR=1 e-06) or is correct?
-To use *STATIC, STABILIZE, FACTOR = 1.00E-05 or *CONTACT CONTROLS, STABILIZE is the same or the effect is different?
Thx and kind regards.

*STATIC, STABILIZE, ALLSDTOL
Using stabilisation in the *STATIC card will add some damping to the structure whereas I guess that contact damping adds damping locally where there is contact.

will lead to global damping...that is to entire model
whereas
CONTACT CONTROLS, STABILIZE
will lead to damping in a particular patch only
Never use both..or system will be error prone
