Hello Foamers,

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.
