Q: How can I remove all viscous damping terms in the damping matrix when computing RAOs?
REV 5.03

A: Do not include any Morrison elements, #PLATE or #AREA commands. Also, the Tanaka damping must be turned off using the A_TANAKA BNAME NONE command, and any panel damping needs to be turned off with the option -cs_cur 0 0 0 .
