Understanding nBlock in explicit subroutine

Dear all,

I am working on a subroutine for the friction coefficient.

I use the loop as following:

      do k=1, nBlock       

            fCoef(k) = user coded...     

      enddo

I get the output to the log file via write(*,*) fCoef(k).

My Elements are C3D8R. So far I did not understand the Output Data. nBlock seems to be 136, this value cannot be changed. Any idea what this value means? I get millions of data output, and it is unclear to me where exactly abaqus calculates the data. My solid elemtents have contact (friction) on two faces simultaneously.

Even if write(*,*) nBlock the outpat data is immense.

 

Thanks for any comment,

Paul
