Hi everyone,

I try to do 2D inversion with a known boudary with the 2025.1 version of Res2DInv. My datafile is attached. The software does not seem to take the layer into account. Below a comparison of two inversions, the constrained one (first screenshot top) and the unconstrained one (bottom). The Legacy version takes into account the layers during inversion (second screenshot).

Does anyone have experienced this problem? Do you know if it's possible to fix it in the 2025.1 version?

Regards,

Angélie.

    I finally found the problem: the z-coordinates are negative and must be positive. Now it works.

    Sorry for the post.

    Great spot! It seems the legacy version is a bit more forgiving when it comes to file format inconsistencies compared to the current release.
