Problem
You receive an error that there are too many soil surfaces or duplicate material text (see examples of error messages above). This is can be caused by using undo (Ctrl+Z) after creating soil layers or soil surfaces.
Solution
Before trying the following, create a copy of the calculation as it might cause issues with the soil layers.
After creating a copy of the calculation try option A, if that does not work try option B.
A) Reload from drawing
In Geosuite Stability, select in the menu Input -> Reload from Drawing. Thereafter, perform a calculation.
If this did not resolve the error, remove the geometry for the soil surface and/or material geometry that is causing the issue and then select Input -> Reload from Drawing. Run a calculation.
B) Updating the drawing inside a CAD software
Navigate to the project folder, and go inside the STABGRAF.RIT folder.
Make sure that you have created a copy of the calculation before starting this.
Open the file that is called {CALCULATION_NAME}.dwg with a CAD software.
If there is an issue with the soil surface, then there is probably a extra polyline for the soil surface. Remove this extra polyline.
If there is an issue with duplicate material text for a layer, then there is probably a extra material name for the material layer that has issues. Remove the material name for this layer. In the error message it often says "Error, there is 2 number of MATE7" or similar. In the CAD software, you can find out which layer this is by checking Layers.
If you still have a issue, notify the support and attach the stability calculation file with the support message.
