Hello,
I have a problem and I would be thankful if you could guide me or at least give me some points that I could solve the problem, because my problem is related to the GeoStudio (Seepage) software. I want to analyse the model in both Plaxis FEM 2D and Geo Studio, but at first I want to check with GeoStudio (Seepage) software.
I modelled a sloped area, but every time I am analysing it is showing me errors that I was not be able to solve it until now.
I drew the “Slip Surface” by entering the “Entry Range” and “Exit Range” in different definitions, but every time it showed me the same error E984 and E998 (attached picture “GeoStudio Errors”), as I attached the model in the model in the following. The updated model is not the exact slip surface that is shown in the attached pictures, but any way as when ever I changed the location, the same as the attached picture “Definitions 01”, the error was the same.
Could anyone please kindly guide me how should I solve the problem and give the points to remove the error and achieve the result.
Thank for all your guidance and support,
I look to hear from you,
