How to install IHFOAM 1806 in OpenFOAM 1806? I know that some functions in IHFOAM are included in OF 1806. I want to use IHFOAM to generate wave. Should I install IHFOAM 1806 additionally? If so, how to install it.?I foud it different from the old version of IHFOAM.

Quick answer: IHFOAM should be already integrated into OpenFOAM v1806, it should not require any additional installation steps.

Hi Robin86,

It is already integrated in OpenFOAM-v1806!!!!

Type:
cd ~/OpenFOAM/OpenFOAM-v1806/tutorials/multiphase/interFoam/laminar

Please, take a look to any of these tutorials:
- waveExampleCnoidal
- waveExampleIrregularMultiDirection
- waveExampleSolitary
- waveExampleSolitaryGrimshaw
- waveExampleSolitaryMcCowan
- waveExampleStokesI
- waveExampleStokesII
- waveExampleStokeV
- waveExampleStreamFunction
- waveMangroveInteraction

Thank you for your reply. Actually, I learn about the integration of IHFOAM in OpenFOAM-v1806. But I don't know how to monitor the free surface of wave through IHFOAM. I have already run some example cases in laminar folder. None of case monitors the free surface of wave. I want to draw the curve of wave elevation and time in specified location. Could you tell me how to realize this in IHFOAM? Could you recommend some paper or informatino to me? I am new here and feel sorry to bother you.
Thank you very much!

Please, feel free to ask anything you may not understand, it is one of the best ways to learn things.

We have added some monitoring tools in the controlDict (free surface sensors) to be able to track and draw the free surface elevation in time in a specific location.

Please, take a look to the end of the controlDict:

Thank you for your reply. Actually, I have already seen the controlDict file in the case waveExampleStokesI. Ater running the case, I only get the alpha.water data along the line in a specified time step. I want to make sure the elevation of the wave in one specified location in all time steps. I want to draw the curve, whose x axis is time and y aixs is wave elevation. How can I realize this? Thank you!

Hi Robin86, I'm facing the same issue at the moment. Did you mange to create the plot with xaxis = time and yaxis = elevation?

[IHFOAM Team]

Hi Robin and DarT,

You can create a post-processing code in any language that you feel comfortable (matlab, fortran, C/C++, python, ...).

There is nothing extraordinaire in how to get the free surface evolution:

For your case, I would recommend to go into the post-processing folder, and loop over all the time steps; in every time step, multiply each cell height by the volume of fraction and sum them up. Add the final result to a matrix that can resemble like M(time_step,free_surface_elevation).

Finally, make a plot in which, "time_step" is in x-axis and "free_surface_elevation" in y-axis.

Best Regards,
IHFOAM Team.

Thought that was the case! Thanks for your prompt reply.

If anyone reading this wants an R script to do it then give me a message

I think it is the convenient thread to ask my question.

Is it possible to do wave-current simulations using IHFoam capabilities? If so, is there any tutorial available?

I would appreciate it if you would kindly give me some hints.

Kind regards,
syavash

Hi, I am also curious about this topic. In fact I read the literature in which they developed the solver to solve wave and current interaction. However, still don't know how to set it.

[IHFOAM Team]

Hi kimy and Ehsan,

... solve wave and current interaction....

We have not released the code to solve waves+currents.
Check this:
- Wave-*‐current generation with OpenFOAM. Application to coastal and offshore structures

- Wave and current interaction with moored floating bodies using Overset Method

Please, send us a direct message if you are interested in a potential collaboration.
