I have a beam which is moving according to a dynamic force. In the environment where the beam is moving there is fluid. Therefore, viscous force is exerted to the beam due to the viscosity of the fluid. Now, I would like to implement the viscosity of the fluid in the model so that the beam senses the fluid. What is the easiest way for doing that?

I thought about using the viscous damping which is normally used as the stabilizer of the solution? But I was not sure if the net effect is going to be the same as a real viscous force. Besides, when I use Dynamic, implicit type of analysis there is no place where I can define any damping for the solution. Is there any other easy solution for this problem?

Thank you in advance for your time.
