Hi,

The model has been created from two separate model including them in a new file, do you have an idea to solve the problem?
I tryied to "suppress" any parts step by step but the model does not work.
Thanks
Maurizio,
Based on the line before the error message, your model is crashing the software when Part 1 is being loaded or when the next part is being loaded. If you have a natural frequency analysis (modal) that does run successfully, you can look at the log file from that analysis. Is the line in the log file after the line "Part 1: ssssssssss elements" refering to part 1 or the next part? It probably says "X number of elements" in which case you know that it crashed while working on part 1, or it will say "Part N: ssssssss elements" which is still ambiguous whether it crashed on part 1 or the next.
Other than that, it is hard to know what caused the crash. Obviously, take a look at the input for part 1 and the next part to make sure the input is correct. I suggest that you look at the input while using the "Model" unit system; that is, your personal unit system that you created. Or maybe you want to use the Metric (SI) units to check the input?
John,
many thanks for your promt answer.
I tried to duplicate Part 1 as a new part and delete the old one, I have the same problem on Part 2.
If you do the same on Part 2, the problem appears on Part 3 and so on.
Moreover I have translated the data base to Csv files and I have noted the Part 12012 in Element file...but in the model that part does not exist!!!
I need to solve this problem asap; I know that a possible way is to build new model but it takes too much time.
if useful for investigation, at below address you can find the archive of the analyzed model.
