Capturing oscillations of a hyperelastic pipe- OpenFOAM and CalculiX

[mishal49]

Hello
I am working on a collapsing pipe simulation using OF and CCX. The pipe deforms and I have remapped it several times to obtain an inward deformation however, I am trying to capture the outward motion of oscillation. Is there a setting I could change or apply an opposing force of equal magnitude to the one sent by the fluid using preCICE to prevent touching and initiate outward motion?
Any ideas on how to go about this perhaps?

Would appreciate y’all’s help

I guess you could use the Actions feature to manipulate the values you are exchanging, e.g., by adding a constant offset. Documentation: Action configurations | preCICE - The Coupling Library
