Thank you for your response.

I tried both your suggestions and I am getting the same error for this problem I even tried it even for a 3D case and still getting the same error. I am sure I am doing something out of the ordinary for it to happen like that.

I even tried it with bejibattjes tutorial cases and had the same thing happening.

Is it possible for you to share your topoDict and controlDict file for the problem? Or is there any other file I should be thinking about?

Link for the problem setup:

Thank you
hello edwubraheev,
I have the same problem like you. I found that it might be caused by the decomposing method. the scotch that you use will cut overtopping face and then some faces in your overtopping face will be boundries. It will be sloved by simple method. but it is too much consumed in simple way. I still have no better way to slove it .

Hello Niels
I found that the overtopping utility is affected by parallel ways. In other words, the soctoch method will decompose the whold computation domain (overtopping face) and then some original internal face will become boundries. so it will fail in this situation. like this Overtopping function. But it will work well in "simple" parallel method. I don't know if my thought is correct and if it is right, I still have no better way to solve it.

Thank you

I am now using Waves2foam as part of my research project on breakwaters. I have encountered some problems with the overtopping function, which I have implemented using the notes on the manual and one of the answers in this forum. The OpenFOAM version I am using is 2.3.0.

Attached I send a screenshot of the error message I get in the first iteration for waveFoam. At the bottom, where it says "in file /home/yl1181/OpenFOAM/... ": that directory does not exist. When I run the same case in different computers I also get non-existent directories under the following format: /home/foam/OpenFOAM/... .

Here I attach a sample basic case consisting of a flume with a slope and a box inside. It would be great if you could have a look at it and give me some advice on the case and what could be causing the error. The case runs perfectly without the overtopping function.

Additionally, I would like to have some information on how to apply porosity in waves2foam. My next stage would be to remove the box and replace it with the breakwater structure and to include porosity. However, I am a beginner with code in general and OpenFOAM and waves2foam in particular; I get quite lost without sample dictionaries or tutorials.

Any help is very much appreciated. Thank you!!!

Hi! Did you solve the porosity problem by chance? Did you insert the porous rubble mound in the domain?
