Flac is a complex software, but the manuals can help you very much. They are very detailed. In the example application you can find "axial and lateral loading for concrete piles" "excavation in a saturated soils" and "Impermeable cassion wall with pretensioned tieback"

Thank you.

Thank you.

Hi Ahmed,

as others have noted; FLAC can be quite complex. Although the graphical user interface has steadily improved over the years and their are significant advantages in some of this complexity. The programming language FISH is particularly useful. FISH programs can be used to record useful information such as loads and displacements as well as running multiple analysis cases in a parametric study, e.g. over night or over a weekend, by creating a file that runs a series of analysis, recording and exporting the results for later review.

My advice would be to spend a little time getting familiar with FLAC prior to looking at the pile problem you want to investigate, which in itself sounds like it has some complex aspects to it. In particular you might find it useful to look at some unrelated problems such as bearing capacity and slope stability. With these simpler problems you can compare your results with some hand calculations, which is a useful learning exercise. When you start looking at you pile I would also suggest starting simple and adding complexity incrementally rather then trying to look at everything straight away.

Good luck, Damian.

Thank You Damian this is very very helpful.
