xueyen New Member Lim Xue Yen Join Date: Jul 2019 Posts: 2 Rep Power: 0	Hi, i wanna ask how to determine the spring coefficient for my simulation? Spring Coefficient that i used in this simulation is to connect my ship hull with the rudder. My simulation is related to maneuvering of vessel (i m using box geometry in flow 3d) with dimension L=0.8m. Mass density is 550 kg/m^2. Is any formula to determine the spring coefficient? And my simulation kept showing pressure iteration diverging and running from 0% straight away to 100%. What is the problem causing this? Please help me. Thank you.
