Making Wave in free surface flow
Hi all
I am trying to simulate a ship on free surface flow with sinusoidal wave that's made by wave maker. How can i simulate this sinusoidal wave as a boundary condition for investigate the motion of ship? Thanks Best regards. |
There are some posts on this forum about setting ocean wave boundary conditions. Do a search for them on the forum.

hmm well the closest i've done is a sinusoidal BC for a multiphase slug simulation... What i did is to calculate the height of the water with the sinosoidal CEL expression; then at the inlet BC i set the volume fractions of water and air to depend on an "if" cel expression; if y > (calculated height) , 1,0. that should set the air fraction to 1 if it's over your calculated height, and after yo set the water volume fraction to a similar expression you should get that sinusoidal BC.
As glenn said tho I'd check all the posts in the forum anyway to see if there's something more applied to your case. |
Thanks mauricio.
I'd check all the posts in the forum about this, but i didn't find any useful things. Best regards |
