I'm conducting an implicit dynamic (quasi static) analysis.
My problem is actually static, but in some of my experiments, dynamic behaviour has occured. I have it displacement controlled by using a rigid plate
I can use in the step: Application: quasi static and then load variation
will change from instant to 'ramp linearly over time' or I can use smooth
step in the amplitude options (0 - 0 and 1 - 1) but what is the difference?
Whenever I select smooth step, my solution won't converge, but it will when I select quasi static application in the step. My results are now 1% - 3% off and
kinetic energy is less than 1% of the internal energy. But still curious what they would be with a smooth step IF there is any difference.
