Production of three-dimensional stratigraphic model

[hadis_masihi]

Hello
I output the 3D lithology model. But with the same data I can not run the stratigraphic model and I encounter the following errors

Do you have at least three points for each stratigraphic unit?  Unlike lithologic modeling, the stratigrahic grid interpolation requires at least three points to estimate a surface.

Based on the error messages, it also seems like you may have a unit called "undefined" in the Stratigraphy Types Table.  Deleting that from the Stratigraphy Types table may resolve the problem.
