Moove Part Until in Contact
(OP)
Dear all,
Is there an elegant way to move parts in a specific direction until they are in contact with another body?
Essentially I need to press two parts upon each other in force control. However, as they are separated in the beginning, I first need to move them until they touch each other before I can apply a force boundary condition (using Abaqus Standard).
Currently I am first using a displacement boundary condition, but this is one of the most frequent sources of error (with the displacement either beeing too large or too small).
I thought I had even seen a specific command for that purpose, however, I couldn’t find it anymore.
Kind regards
Max

For any future readers with similar problems:
The command I was looking for was *CONTACT CONTROLS, APPROACH, however, I couldn't find anything about it in the current Abaqus documentation.
Instead I am now using spring elements to constrain the moving part when approaching in force control.
Kind regards

would be an option. Have a look at the Keyword Reference Manual for details to this keyword.
Soft springs, global stabilization or the quasi static procedure would also be possible.
