SOS!!! (Simulation over simulation)

Thiago Meyer Apr 2, 2015 12:44 PM

Hi, everyone,

It is possible to make a static simulation based on results of a previous static simulation??

In the first simulation, the thin sheet will deform elastically, as illustrated in pics 1 and 2.

Pic 1

Pic 2

Then, with the part in this state, a second force will be applied (picture 3).

Pic 3

It is posssible to do this in solidworks? Can i save the results (stress and displacement) of the first simulation and starts a new one, resulting in a sum of the stresses applied by both forces in the part, sequentially?

Are you still only applying forces (not changing to maintain the displacement that results from the first simulation)? Why can't you simply apply 2 forces at the same time? A+B = B+A
If you truly need them separate my understanding is that this can be done with the non-linear simulations which allow you to apply forces in a specific order and solve in between. I'm sure someone with NL experience will chime in shortly but that's where I'd start looking in the mean time.

  Hi, Chris,
  
  The displacement must be achieved before the aplication of the 2nd force.
  
  I´ll look for non-linear simulation. Thanks!!!

    It is pretty straight forward in NL analysis to do what you are seeking. That being said it is also true that nothing is easy in NL when you are new at it.

      Thanks you too, Bill!!!
      
      I´ll make efforts to learn NL analysis quick as possible.
      
      Best regards to both of you!

  can confirm, nonlinear is the only place you can sequence a loading condition

    Thank you too, Jared.
    
    NL simulation is quite more complex than static! Can you guys sugest good tutorials about that subject?

      That´s a good SW Simulation book??

        don't know much about the book, we generally recommend our nonlinear training and mentoring so that you can work directly with someone
        
        it looks ok though
        
        lots on youtube and resources within the software and solidworks kb should get you started
