Modeling time varying force




I am trying to use NX to model a time varying force. Specifically, I am trying to model a structure subjected to a gust of wind at 100 mph for 3 seconds.


Can this be done with the advanced simulation tool, or does this type of modeling require the response simulation add-on module? If you can do this with the advanced simulation tool, how do you account for the time?


Thank you....

Hi Michael,


first of all you have to use Solution 601 /129 or 701 to solve problems with time characteristics and large gradients of loads in short time.

Mostly you are able to specify a time characteritic in solution => case control

-  strategy parameters and

- time step definitions and additionally

in load description, (may be a pressure  with time domain table or field to describe time chraracteristics).


In my opinion you can do it in advanced simulation without response simulation. It depends on your problem.
