ESLTIME in Optimitzation using Radioss, number of itereations
Hi,
I'm trying to run a topology optimization through radioss using the ESL method.
As far as I understood it is possible to use the capabilities of optistruct through the bulk data entries in the radopt file. Is that right? And if so, how can I use the ESLTIME command? I would like to compare the results of an optimization using the default settings and with ESLTIME type 2, i.e. esl generated at the peak points. I entered the necessary bulk data in my radopt file but it does not make any difference at all.... How do I fix that?
In addition my optimization seems to run only a certain number of iterations. In the Solver View I get a message saying " LIMIT ON ITERATIONS REACHED.
FEASIBLE DESIGN (ALL CONSTRAINTS SATISFIED)" . It is not clear to me if the outer loops or the inner loops are meant, as the outer loops do not reach the default value of 30. And in this case, how do I know if the optimization has converged? Is there a way to increase the number of iterations?
Any help would be very much appreciated as I hit a dead end and have no idea how to fix my problems. I attached my starter, engine and radopt file.
Thanks very much for any help in advance!

Hi
maybe this is what you need to add cards of Optistruct.
I hope this is helpful

Hi,
thank you for your help!
I did try that but it did not have any impact on the generated esl subcases. Not sure if not further information needs to be given via the bulk data entry and if so, which one...
Best wishes
