PMM test in OpenFOAM

Thaw Tar · March 12, 2016, 10:51

Hi everyone,

I want to do the simulation of planar motion mechanism (PMM) test for an autonomous underwater vehicle (AUV) using OpenFOAM.

I want to simulate the flow field around AUV which is fully submerged (single phase flow) using PMM procedure. I want to give the forced oscillations of yaw motion to the AUV for certain periods to create the sine wave motion using dynamic mesh in OpenFOAM.

I searched for it and found Ship Design Analysis (SDA) using solid body motion. But it has only roll, heave and pitch motions. Thus, I want to know whether I can use this technique, by changing the coordinate system of the AUV to create yaw motion instead of roll. I am also not clear about whether I can use SDA for single phase flows.

Or do I need to re-create another SDA that has the capability of doing yaw motion by myself? I am not good at OpenFOAM programming.

Thanks in advance,
Thaw Tar

Hii Thaw Tar..

Am also working on the same problem. were you able to solve this
