Hi to all,

I’m performing a slope stability analysis in FLAC 8.0 in which I’d like to replicate the dynamic action related to a water wave impact on the slope. The idea is to use the function *apply sxx* along the (i,j)-cells interested by the wave impact, by applying different values of stress (i.e., sxx) per each time-step of analysis.

I realized that it doesn’t make sense to reach the equilibrium using the **solve** command. In fact, my idea is to replicate the dynamic action of water waves impact on a slope by the use of a pushover analysis. This latter consists in reproduce the multiple and subsequent applied pressures on the slope, that, in “real-life” are related to a dynamic phenomena (which lasts approximately 30 seconds), but in the pushover analysis (i.e., FLAC model) I replicate these actions referring to separate (but subsequent) static calculation steps. However, it doesn’t make sense to reach the equilibrium, because it would mean considering the applied pressures not as instantaneous but as applied pressures acting over time.

So, I’m trying to use the **step** command instead that the **solve** one, but now the crucial question is: how many steps should I consider for my purposes?

I’m not performing a creep analysis, so the steps are not directly referred to the real time.
