Coastal walls (dyke) are one of the methods of protecting the coast against coastal erosion and destructive forces of waves. The purpose of this study is to simulate the wave collision with the coastal dyke and compare the results with the laboratory model. Open FOAM open source software and K-ω SST turbulence model were used to simulate the amount of wave consumed by the coastal dyke. Taking into account the different conditions for modeling, a total of 45 experiments were selected to run the program. Modeling was performed in two general conditions with and without structures and for 3 heights of the structure, 3 different positions of the structure and 5 wave heights. The results showed that the absorption of forces has increased compared to the unstructured state and it can be said that the presence of the structure has been able to play a role in the dissipation of wave force up to 10 times compared to the unstructured state. The intensity of force changes in the structure is a function of wave height and this effect decreases with increasing wave height. Under different wave heights, the farther the structure is from the wave generating tank, the less force is applied to the structure.
