  • in reply to: STL porous media loading #8999

    Dear Jan,
    Dear all,

    sorry for the late I tried several tests in these days. I noticed that even though the STL file is intended to be interpreted in micrometers, it is treated as dimensionless in my case. Initially, I requested a number of cells that was too high for my RAM, so I started to reduce the domain size, and eventually, I created a very basic example.
    I created a 5x5x5 domain
    The domain is essentially made up of cubes, so I expected the lattice to conform to these dimensions as well. However, I noticed that the mesh tends to ‘contain’ the domain rather than adhere to the edge, with the border vertices being both internal and external in the surrounding cells. Therefore, I have a series of questions, as I am working with porous materials where every approximation is significant:

    -Is this behavior normal, or is it due to my poor use of the library?
    -Is the excess always just one cell?
    -Depending on the refinement (one slice in the figure ), it is not symmetric. The test presented here is at a 1:1 scale, but the ‘shift’ of the vertices is 0.25. Is this also due to a mistake in the library, or is it justified?
    -Is there a way to force the boundary mesh to adhere to the vertices of the porous medium once they are given as voxels, thus theoretically already cubic and easily adaptable in structure?

    Thank you in advance,

    Dear Adrian,
    thank you for your feedback! I will check the correct linking of dependencies.
