Hello, I was trying to do the Free Surface tutorial, but I cant find where to set up the HOF in the initial conditions.
Thanks

Hello,.
If you go into the Initial Conditions part and select any of the volumes that are already 100% fluid, you will able to assign HOF to them
Ok, now I see what I was doing, In the initial conditions I was selecting the surfaces and then trying to apply the HOF, But I have to select the volume tool instead of surfaces.
Thanks for your help.
Good Day Mingyar
Sorry to hijack this thread but we are interested in conducting free surface simulations as in the link below.
https://www.youtube.com/watch?v=WNKHf937Qt0 (I assume you are attempting to do a similar tutorial)
What version of Simulation CFD do you require to do this?
Thanks for the reply
are you using the base level of CFD 2014?
On the Autodesk website there are three options.
Simulation CFD 2014
Simulation CFD Advanced 2014
Simulation CFD Motion 2014
I would like to make sure what the correct version would be before continuing.
Thanks for the quick response. Do you know what the lowest level of CFD 2014 can be used for the free surface simulation?
We are not interested in simulating mechanical parts in motion (fans, pumps ect.) and CFD Motion might be out of our budget.
Im not sure and its not on this link http://www.autodesk.com/products/autodesk-simulation-family/compare/cfd-products
But maybe you can download the 30 day free trial of the basic one and see if you have the free surface option.
Thanks for all the help!
I might have to download the basic version to see, unless someone from Autodesk can let me know.
Hello
i upload a picture like simulation TV's product
"motion and free surface "
but when i setting in CFD 2014 it always have some problem
like:have some fault or haven't the wave
so can you teach me how can I setting and the result is correct
hi Product Support
i have ask the question so long time
have you any free time can help me solve the question
thanks
i have upload the data in autodesk 360
Hi,
Would you mind sharing the CFZ on here?
Could you also be a little more specific about the error or issue you are seeing?
Kind regards
Jon
thanks your reply first
here i share my data
the model is the same with simulation TV's model
but I cann't get the some solve
I think maybe have some setting is wrong
so, can you teach me how can I set the correct setting
thank you !
Hi,
You also need to model the air above the water.
As a material it will be assigned water although it will not be assigned a Height of Fluid Initial Condition so it will actually be treated as air once you start the analysis.
It is highly likely that you will need a far finer mesh - a uniform mesh is ideal here.
Kind regards,
Jon
I just wanted to clarify one thing that Jon said.
The space above the free surface isn't actually air or any fluid. It is technically a void in space where no fluid occupies. This is good to keep in mind because this isn't a multi fluid solver just a free surface solver.
thanks for your answer
i need to try some model that you talk
may I have your mail is more convenient to consult some question
thanks
Hi,
Could you help , how to set up the height of water tank, free srface analysis ?
Thank you so much
