integration point calculation order in abaqus

integration point calculation order in abaqus

(OP)
Dear All,
I have a very simple question. I have searched a lot but I couldn't find a good answer to my question. Do you know if abaqus starts calculating the integration points from the first integration point of the first element and when the calculation in that element finishes goes to the second element ? what is the order of integration point calculation of abaqus ?
Regards
Selcuk

RE: integration point calculation order in abaqus

I don't know the answer but I can take a guess. A solver tries to minimize the "bandwidth" of a matrix to solve Ax=B as fast as possible. For that, solvers end up using some form of "Gaussian elimination" technique. So, the "pivots" of each row need to be moved around to give a shorter bandwidth. Bottomline: I do not think a solver starts from the first integration point of the first element and ends at the last integration point of the last element.

You may use one of the subroutines which gives you access to variables like number of element, node number, integration point number, etc. Check the user subroutine manual in the ABAQUS documentation.

I have an uniform mesh that starts numbering of the elements from the bottom left line and the maximum element number is at the upper right corner. in this case when I have printed the integration point order it starts from first element and goes regularly. I am going to model other cases and see but I have searched the manual and there is no answer in it.
Thanks Ice...
