Hi all
In a simulation study, I would like to create an imposed displacement following a certain step in order to finally obtain a graph of this imposed displacement as a function of the displacement resulting from my geometry.
Let me explain: my piece is a slightly domed metal strip 30 mm long / 10 mm wide / 0.2 mm thick. When I apply an imposed displacement (on its thickness) lengthwise, the piece flexes in the middle (see photo). The goal of my study is to obtain a curve of the imposed displacement as a function of the resulting displacement (in red on the photo), the problem is that I have to do 10 simulations with 10 different imposed displacements if I want to get 10 points on my curve.
Is there a way to perform in a single simulation an imposed displacement incremented by a defined value to finally obtain this graph??
Thank you in advance:)

Hello
Yes of course! Launch a design study in the simulation tab, and you will have a banner at the bottom of the window, where you can enter variables. That's all! It's pretty intuitive

Sorry for the double post but one problem often leads to another :/
I have indeed defined the imposed displacement of my static study as a parameter of my design study. In the "variable" tab, I enter my movement as well as its limits and pitch. Then a limit imposed a bit arbitrary because I just want a graph of the imposed displacement as a function of the resulting displacement. I therefore take the limit of the resulting displacement: less than 10 mm (the study does not generally exceed 3 mm). For the rest, I don't choose any objectives. (see photo)
Then in the options I choose "Quick Results" and then click "Run". At that moment a message obliges me to use the results in high quality! Since I can't say no, I'm continuing the simulation. Once the results are in, it is impossible to 'set a local trend chart'. A message tells me that they are not available with a high quality simulation because of the active scenarios, while I was forced to do so!
I tried to do the same thing with the "Table" tab but same thing.
Do you have an idea? Thank you in advance:D

It's been a long time since I've used the tool but it seems to me that you don't need to enter an imposed limit, if you don't need it. Your limits are the maximum minimum values entered.
At worst try by putting 2 min values max and that's it, without steps.
Otherwise, check that your "long displacements" option is enabled in the rdm options.
Enclosed is a quick study that I have done. This should fit with your application.

I managed to get the desired curve!!
Thank you for your advice!
