Hello,
How it is with the vector of a force during a simulation where the geometry bends and therefore the face which you put the force normal to has changed angle slightly. Does the force then keep its vector according to the main coordinate system, or does it change to keep its angle normal to the force face.
Hi!
With a “Force” boundary condition, the force will continue to be applied in the original direction (i.e. the bending of the geometry will not be taken into account).
If you’d like to keep the force normal to the face throughout the simulation, even if it bends/rotates, then you’d need to use a “Follower pressure” boundary condition.
Cheers
Aha, i see. Thank you for your answer!
