Greetings
I have a rather simple question. I want to model a submerged body moving with speed of V in a depth of say 10 meters and want to neglect the free surface. Thus I don't want to activate the VOF Wave model. My question is: How to define hydrostatic/hydrodynamic pressure specially at boundaries? I rather say I want to it via a field function but am not very familiar with the syntax. Thus I don't know how to add position Z in the calculation. Best Regards |

by far the easiest way is to activate vof waves then define a flat wave but set the wave surface to be outside your fluid region so there will be no free surface created nor solved
then you can still use the inbuilt field functions on the boundary otherwise create field functions involving gravity and height which if z is vertical is $$Position[2] |

Thanks for the reply
Yes in fact for such situations I have exactly done the method you said. So all I have to do is to add the position of Z in the form you mentioned. Thanks for the hint. |
