Define a surface by using construction geometry and plot you result on this surface.

Hope this will be helpful.

Hi Mohammad Amin Faghihi Zarandi. I suggest you do geometry update after the solution. this will give you a CAD model of the deformed geometry. After that you may measure the cross sectional parameters.

Cehnpin Hsu WHat do you mean by construction geometry?

Mohammad Amin Faghihi Zarandi

THis one.

Cehnpin Hsu I tried it but it does not work unfortunately

Mohammad Amin Faghihi Zarandi

Lets clearify which part that doesn't work.

(1)Do you mean the deformation result is that you don't expect?

(2)Or, do you have trouble with making a construction geometry?

For (1), it only can show you the deformation result contour on the construction geometry you made. If you need to plot the area, I don't know how to do as well.

For (2), you can refer to the instruction below.

Cehnpin Hsu Actually none of them. The problem is that even I create the surface, I do not know how to find the area. The problem is the hollow space that I want to find its area not the deformed section (shown on the attached file)

Hello,

I have actually exactly the same issue, i'm also simulating a two way FSI collapsing tube in a transient simulation. I need to know the area during all the steps time, did you find your answer?
