User define force function of variable "x"

Hi! 

Is it possible define a force as x-variable function  (not necessary "x" is the time)?

For examble: F = a*x^2 with x = [0 1 2 3 4].

 

Thank you

Re: User define force function of variable "x"

For the implicit structural analysis used by Creo you cannot define a force as a function of an analysis dependent result/measure, only time. However, you can make an independent parameter have control over the value of the force in the force definition.  The independent variable (parameter) is stepped using a sensitivity study, or optimized as a variable in optimization.

Actually time is just an independent variable for CREO, it is not really time, so there is no reason not use use it for X instead.  This is because CREO is implicit and does not have dynamic effects.  Try it that way and you should get the same result as my example above.
