Reply To: Initial Velocity Generation

Good day Pedra

thank you for your recommendations.

As for the curves concerning the maximum value of the integration step and the step of output of the calculation results – they are in the model.

But as far as I understand, if the model uses switching from an implicit to an explicit solver,
then in this case – ls-dyna does not want to fulfill the exact requirements for output of the calculation results specified in the curve.

it not only writes the results “arbitrarily”, but also changes the “prescribed” value of the initial velocity – as a rule, to a greater one.

maybe I’m wrong about something – since my experience with ls-dyna is very modest.

So I hope to hear the opinion of more qualified engineers.
