I am trying to simulate Turek FSI3, where i changed the paramters according to my criteria i.e I changed the fluid properties and solid as follows:
Density of solid (ρs) (kg/m3) =32.9
Poisson ratio (νs) =0.199
Young’s Modulus (E) (10^6 kg/m2) =0.849
Density (ρf) (kg/m3) =1.23 (air)
Kinematic Viscosity (νf) (m2/s) =0.0000147
Velocity= 8 ms-1
Thickness of flap= 0.005m
The problem I am facing is, the displacement is very small. Will you all suggest what cfd parametres should be changed to capture large displacement?
PS: I didnt change the timestep size neither courant number.
