Hi <\/p>\n

I have simulated a hollow cylinder for hydrodynamic analysis. I did physical experiments on the same model. calculated viscous damping and gave as an additional damping in aqwa. when i tried to validate the experimental and numerical results, the trend is seen with actual acceleration and the magnitude is matching with rao based acceleration. how to handle this . Any explanation will be highly useful.<\/p>\n

2. when i calculated displacement from acceleration using fft code it was not matching with the aqwa displacements.<\/p>\n

3. how aqwa calculates actual response?<\/p>\n

4. how displacements and accelerations are related in aqwa?<\/p>\n
