Hello sir, my name is Vamsi Krishna and I am an M.Tech student. I am doing a project on combined trapezoidal and semicircular breakwaters.
In this project, I need to know about porosity for cylindrical solids in the x and y directions. Is this possible? Are there any codes in the REEF3D software that can help me?

Hello Vamsi,
It is possible to create porous structures in REEF3D using VRANS, options B 270 until B 291 are available.
These options assume a homogeneous porosity given as the input parameter "n".

I checked the codes in the REEF3D user guide, but I couldn't find any codes for porosity of a semi-circular breakwater in the y direction.

I might have misunderstood your problem, sorry about that.

The options I gave previously are sadly the only ones currently implement, however if your breakwater is located on the sea bed (the semi-side down), you are not using the sediment transport model and you are using CFD, you could try using the DIVEMesh option T32 to represent your breakwater.

You would need to make your sea bed into a solid, so using S options in DIVEMesh or G 9 2 if you are using geo-data.
In REEF3D you'd need to use S 10 2, S 24 (porosity) and use S 41 in conjunction S 43/45 to prevent the sediment algorithm from running during your simulation by setting the start to after your flow simulation is completed.

Thank you for the suggestions. I will try the options you provided and let you know if they work.
