Doubt about External Flow Simulation

Question asked by Carlos Rivera on Oct 9, 2018

Hi, I'm going to try to be as clear as possible because my English is not good enough

 

I've designed a paddle that needs to be partially submerged in a canal. The paddle moves through the canal, i know that i can't simulate the movement of the paddle instead, i´ve simulated a flow through the paddle. I've obtained the force acting on the paddle.

 

The problem is that i need to obtain the force acting on the paddle when i suddenly change the direction of the movement of the paddle when it is already moving in the first direction. I know that this force needs to be higher than the first but i don't know how to set the parameters for the new simulation.

 

I've inserted an image of the paddle (the computational domain simulates the volume of the canal).Paleta.JPG
