[AgreeU]

My GMSH file is like this, I dnon't how to handle this error.

Hi Yang

BEMRosetta supports .msh extension from SeaFEM/TDyn/GiD software, but not the GMSH .msh format that you include.

The GMSH .msh format covers a wide type of meshes, but If the meshes you use are the classic BEM meshes, just surfaces, created with flat triangles or quadrangles, it may be easily implemented. Please send me some simple samples of know figures and I will prepare a reader in days.

Thanks a lot. I have uploaded the corresponding mesh file and the gmsh file of this picture.

Hi Yang

Thank you for the example. I missed having a picture of it to know what it was about. When I look at the file, I get the feeling that it has a lot of pentagonal panels. Is that possible? If so, I would not be able to reconvert them into quads or triangles without more information.

Hi Iñaki,
Sorry about that. I forgot that these files cannot be opened by BEMRosetta. This time, two models are provided: cylinder and windfloat; additionally, there are images, NEMOH format grids, and some SolidWorks models included. Please note that when I open the grid for windfloat with BEMRosetta, there may be some display errors, but the grid information can still be read. Please use it as you see fit.
As for the grid, I used quads.
Regards,
Yang

Hi Yang

I have prepared a light reader that works well with your samples. It avoids all the .msh features but the strictly necessary.

That's really fantastic.
