Force on a structure in ALE

Post by vshinde »

Hello,

Can you please tell me where is the sub-routine that calculates the force on each moving boundary face in ALE module?

PS: I am trying to separate viscous and pressure forces on a structure in FSI.

Thanks a lot for your time.

Hello Vilas,
You can use the subroutine cs_user_extra_operations-global_efforts.f90 from the directory SRC/EXAMPLES of your case to calculate the total force on the boundary faces or you can use the GUI (surface solution control) to write the efforts.
Then you can estimate the pressure force manually and subtract it from the total effort.
