Amirmasoud Abbaszadegan I used the velocity boundary wave creation method, a 2D numerical wave pool with a simulated isolated wave, but with a wake behind the wave.The wave surface is shown in the figure.

Filippo Maria Denaro Do you know what this is generally caused by, I switched to another isolated wave equation but still have the same problem.

Qiang Xu

what you addressed means nothing for me as I need the details of your flow problem and setting. The wave you described is the level of the water?

Dear Qiang Xu,

Can you show us the wave equation and the boundary conditions?

Ryuzo Horiguchi

Velocity boundary waveform generation (2d, dp,, pbns, vof, lam, transient)：

wave equation:

D:Water depth；

H:Wave height；

c=sqrt(9.81*(D+H))；

u=(H*pow(1/cosh(sqrt((3*H)/(4*D))*(x/D-c*t/D)),2.0))*sqrt(9.81*D);

v=sqrt(3)*pow(H/D,1.5)*y/D*pow(1/cosh(sqrt((3*H)/(4*D))*(x/D-c*t/D)),2)*tanh(sqrt((3*H)/(4*D))*(x/D-c*t/D))*sqrt(9.81*D);

boundary conditions：

inlet: velocity-inlet;

outlet: pressure-outlet;

top:pressure-oout;

bottom:wall;

Dear Qiang Xu,

I respond to your question, although your problem is difficult for me.

If you describe your broblem in detail, someone will help you.

I am sorry for my inadequate response.

I hope your success in your research.

Sincerely,

Ryuzo HORIGUCHI (Kao Corporation)
