Hello Code Saturne team,

I am doing fluid structure insteractions simulations using ALE method in code saturne. How can I restrict the motion of structure in particular direction? Indeed I have to allow structure (cylinder) to oscillate in 1 degree-of-freedom (transverse direction) only.

Please suggest the appropriate way of doing it. Also it seems that the documentation on ALE is under preparation?

Thank you very much for your support.

hello,
you can try to give an hight stiffens to the two direction that you want to fix, and eliminate forces applied in these directions. (ex: for a needed motion in y direction: fluid_fx=fluid_fz=0 and kx,kz>>ky)
best regards.
