This is a repost from a discussion I started on Contributed Cases.
I am interested in simulating a membrane stretching due to collapsing channels in response to negative pressure. These channels are independent. The channel where the region of interest is located is in contact with a fluid.
It is an enclosed device with three channels, two channels to generate membrane deformation (the membrane is bound to the elastic body) and a middle channel with an inlet and outlet for continuous liquid flow.
The results will be published, hopefully.
I started working on the model in ElmerGUI.

Hi
If you know the pressure of the fluid domains there is no need to mesh them. Just apply "Normal Force" (same unit as for pressure) on the fluid walls.

Thanks for your suggestion Peter, I usually complicate things.
Can the negative pressure channels cycle on/off using a function?

Sure, for example

Code: Select all
$a=1.23
$w=4.56
Normal Force = Variable time
Real MATC "a*sin(wt)"
