Flapping foil

antieskmartin · August 30, 2017, 06:38

Dear Samadhi

I am also working in the field of flapping foil system. I followed your set up,

But unfortunately, I found an unexpected displacement of foil in the X

the direction where it is not allowed. The foil is allowed to oscillate coupled

motion of heave( with respect to Z direction) and pitch (with respect to y

direction). Since the foil is moving in the X direction the overset region is

moving out of Overlap region and cause an error.Could you help me to figure

out the error. Here I am attching the images

Which software are you modelling this in?

Dear Glenn

Thank you for your interest

I am using Star CCM software

Then try the StarCCM forum.

How have you specified the motion for the heave and pitch?

Yes the foil is allowed for coupled motion of both heave and pitch.
But I have tested with heave alone and experienced the same issue.
