Sir, I want to know that how can I add complex geometry in reef3d as 'stl' format. If I make complex geometry in a CAD software and export it to .stl file, then how can I import it to reef3d.

1. name your .stl file as "solid.stl" and put it in the working directory.

2. add following line to the control.txt
S 1

3. run DIVEMesh for preprocessing

check the DIVEMesh user manual section 1.9 for more solid geometry options...

Thank you. Do i need to import whole domain with complex geometry or i have to import only structure?

[valgrinda]

That would be up to you. You can combine a solid.stl file with other solid entities (see S options) or with natural topography, see G options in DIVEMesh.

Thank you sir

Hi,

Have you solved your problem？ I have encountered the same problem as you.

I want to simulate the erosion of a complex bridge pier in the water. And I want to add this structure to a specific position of the rectangle, but I don't know how to set it. Or how did you solve this problem.

Thanks in advance.

Without knowing further details, use:
S 1 1
to include your stl file in the grid generation

Use:

S 7 x y z

to move the structure to where you want it to be. The stl file has a value for that defines the origin of the coordinates in that file. The x y z values in S 7 help you translate (move without rotation) the origin of the imported stl file so that you can place it where you want it to be
Hope that helps

Thank you sir. I have solved this problem. ：D
