Hi,
I am running ANSYS on batch mode to simulate a composite lamina (one
layer) with some pattern is cut through, like 4 circular holes.
I would like to do this analysis for different angle of fibers, so I
used SHELL 99 and applied *DO and *ENDDO. But after reading the output
with Matlab I perceive some errors occur in not the first iteration
but all the single ones after the first.
The thing I have done was reading the displacement of each node around
the holes which were 24 nodes each hole, for 4 holes, total of 96
holes. The displacement vs node number plot for the first iter which
fibers are along the zero angle direction I have a smooth and nice
plot but for the second iter I have massive error in the first 4 nodes
(node1-4) then for third iter these four nodes error shifted to the
second four nodes (node 5-8) and depends on number of iterations it
moves forward.
At the beginning I though this error may happen, since after each
solve iter I have just cleaned the mesh and boundary conditions while
I should have cleaned the cash by /CLEAR. Nevertheless, I still get
the same error which it seems a matter of remaining calculation in teh
memory as I do not have it in the first fiber direction no matter at
what degree I start the simulation.
Please let me know if can help me to solve this problem!
Thanks,
