How to generate a real landslide mode about titan2d HOT 4 OPEN

Dear Henry,

Yes, Titan2D can only handle two simple forms for now. It shouldn't be very difficult to implement and we have discussed it earlier, but it is not clear when we will have time to add that.

Thanks,

Dear Nikolay,
Many thanks for your reply. Furthermore, will you give me some suggestion about how to perform a landslide with complex boundary?
May I import the Piles information from a file?
Thanks a lot!

Yes, you can try to use a set of piles to approximate more complex geometry.

The input file is a python script so you can add it within your input script. Basically you need to add piles multiple times with modified arguments for addPile method:

piles_xy = [
    [644956.0, 2157970.0],
    [644936.0, 2157970.0]
]

for xy in piles_xy:
    sim.addPile(
        pile_type='Paraboloid',
        height=30.0,
        center=xy,
        radii=[55.0, 55.0],
        orientation=0.0,
        Vmagnitude=0.0,
        Vdirection=0.0,
)

The problem is that I don't think it will handle overlapping piles correctly, particularly the initial material volume. Current stable release has a bug in calculation of cylindrical piles volume by factor of two results are not identical but qualitatively somewhat similar (parabolic pile are ok and it is already fixed in master).

Thanks a lot.
Yes, there may be overlapping of piles with cylindrical or parabolic piles. If the rectangle pile can be used, it will be ok for a landslide with complex shape which can be discrete a series of rectangle piles.
Thanks a lot!
