If I understood the manual correctly, this can be done only in Abaqus/Explicit via user subroutine VUSDFLD. More detailed information is given in *DAMPING https://www.sharcnet.ca/Software/Abaqus/6.14.2/v6.14/books/key/default.htm and sect. 1.2.22 https://www.sharcnet.ca/Software/Abaqus/6.14.2/v6.14/books/sub/default.htm The example in the second link can be used as a sample.

Dear Dr. Victor J. Аdlucky

Thanks a lot for your answer.

Mahsa

Good wishes.
