Hello, -You entered the bed coefficient of 10000 t/m3. You may have made a unit error, please check. -As Nedim Bey stated, since the column is not defined in the system, there is a problem with the basic thickness control. -There were problems with some of your programmatic settings in your model, we fixed your settings, but you should review your analysis settings. (Earthquake zone etc.) - Solve the model with the superstructure interactively, when it is solved without interaction, there is a problem in the model. We will work on this issue and make the necessary arrangements.
