"Maximum number of time increment cutbacks reached"

Hi Alessia,

Please check all units you are using in your model.

Scale all the components to meter (1000x) and your model will converge properly.

Please mark the answer as correct if works for you.

Thank you.

Hi Bobinson, thank you. It works!

I have two more questions:

1) How do you understand if the component is in [m] or [mm] (since hyperworks doesn't display unites of measurement)?

2) Why was it the cause of non-convergence?

Thank you

Hi Alessia,

Thank you for the feedback.
1) You need to use consistent units in HW (which means OptiStruct doesn't have how to define any Unit System). Please see attached an example for each Unit system I took from the internet
2) Because you were using a very high value for load, and using very small elements. So, using the increments you were using is not possible to attend the convergence tolerances.

Thank you,
