Hello All
I calculate the waves of a water tank and then damp with a structure the waves. At the beginning I start with a single excitation an then wait and just let the gravity do the job. My model is similar to the sloshing tank example but rebuild with the FSI. I added then a bar which is made of rubber with a damping loss factor.
Now the problem: When the young modulus is 10e9 the model works fine, but the bar moves only for um. When I reduce the young modulus to 1e9, the model didn't converge. Does anybody know how I can make this model more robust? I would like to see the bar swinging within the waves and set the damping factor an the size of the bar to optimally damp the waves.
My model is attached.
