TAGGED: apdl, error, iterations, macro, optimization
April 23, 2023 at 10:20 pmGiacomo GelmettiSubscriber
For my master thesis I have to run several iterations of an optimization macro in ANSYS APDL.
Sometimes the code could not mesh correctly the geometry and it stops, so I must click on PROCEED in order to skip the error.
Are there any ways to skip automatically errors? What could I add at the code?
I hope that the question is clear!
Thanks a lot for the cooperation,

If it MAPDL, try to launch macros in Batch mode

Thank you for the reply!
Actually I tried Batch mode, it stops in any case... in the .out file it shows that the following error occured:
There is at least 1 small equation solver pivot term (e.g., at the UX
degree of freedom of node 6778). Please check for an insufficiently
Is it possible to force ansys to skip this error and proceed?

It means that your model is not fixed. Try to find node number 6778 and see why it flies away in the x-direction.

I know which is the reason of the error, but actually since it is an optimization procedure with several iterations is not possible to modify the single nodes.
I just need a code to skip the error and force the program to go on because actually if just 1 iter does not work is not a problem.

I have never tried, but have a look at the help of /NERR command.
It seems to have an option to avoid aborting on error.
Another (not tested) idea could be to separate the execution on two different input files: the main one, making the loop, just calls (with /INPUT,,....) the subordinate input file where the solution takes place. If this file fails, it will simply exit without providing results, but the main file (maybe :-) ) will not stop.
