Which code to go for free surface wave modeling..
 
Hi all,

I am thinking about getting a cfd software for free surface water wave modeling. I have tried Fluent, but it has only 2nd order upwind numerical scheme for use.

I would like to know other users' opinions regarding STAR-CD's performance on free surface wave modeling (interaction with structure etc.)

Thanks in advance..

Star-cd is ok i guess, but you wouldn't want to use it for free surface modeling these days anyway, not with star-ccm+ around. That has got all the comet stuff in so it is really good.

Thanks John.. I will explore more about ccm+.

Don't write off Fluent. It has a lot of options for modelling free surface waves, and in my experience does an excellent job of it. It is not necessarily easy to do it with Fluent, but the results tend to be very good.

Thanks Charles. I am also happy with the performance of Fluent. I am just exploring more options. Actually, the cost for license is also part of my consideration. I have heard that STAR-CD is much cheaper than Fluent. What about CCM+?

I've used CCM+ just a little bit. I quite liked it, and locally at least it seems to be less expensive than Fluent.

An open source code that seems to be gaining momentum is called OpenFoam.

I am not sure if it would do your free surface wave modeling, but, it's free and scales nicely if you are using parallel computing/HPC.
