+    <value>DAM was unable to generate a valid soil profile 2D when combining the surface line given in the CSV file with the soil profile given in the STIX file.
+    The most plausible underlying cause is that the geometric intersection results in residual soil layers with extremely small thickness (thinner than 1 mm),
+    which are not supported by the algorithm.
+    If the surface line provided in the CSV file is intended to coincide exactly with the surface line defined in the STIX file, 
+    ensure that both surface lines contain the same number of points and that their coordinates correspond one‑to‑one.</value>
