Hello again.I draw a cylinder with plates(underwater) at spaceclaim and i added disks from aqwa with D, Cd and Ca.I put Ca=0.0000101(very small)  and…what values of Cd should i put?Must i double the default values first and use for examples values from 2.28 and more? Do we assume that those disks are immersed at both sides ?Did i do well that i used really small added mass coefficients for all disks??

2)The values of Cd do they depend on the waves and the  depth where  the heave disks are?As they depend of the square of the water  particles velocity,how do we know which exact values of Cd to use?Or do we just use hypothetical values of Cd?

Thanks a lot!!!
