Certainly, here's a modified version of your statement:
I am currently engaged in dynamic analysis of slopes using FLAC 2D, focusing on various subsurface conditions. During the solving process, I've encountered two significant challenges:
1. Bad geometry while solving
2. Factor of Safety (FOS) Calculation (max no of steps reached)
I have tried by changing the limit steps of FOS, I have applied initial condition and 'set large' mode for bad geometry but no result.
I would appreciate any guidance or insights on overcoming these challenges to improve the reliability and accuracy of my analysis.
