    FLAC vr. Plaxis

    I just checked, and the option in Plaxis is actually called "updated mesh". From what I understand, it updates the mesh during solving, which is what FLAC essentially does naturally in its Lagrangian analysis.

    FLAC vr. Plaxis

    Yes, that's exactly what I mean. The large deformation analysis in Plaxis narrows the gap between what it can and cannot do, when compared to FLAC.

    FLAC vr. Plaxis

    I can't comment too much on the coding part of the programs, but Plaxis is by far the easier program to use. The biggest disadvantage of FLAC is the tediousness of it. With FLAC, you must generate your grid mesh first. You must plan on the size, shape, and mesh density of your grid before you...

    Mimicking road surfaces in FD and FE models.

    Using c=2kPa(0.3psi) helps, a tiny bit. I still get more than 50mm deflection at the "road" surface. If I bump it up to c=50kPa(7psi), I get more reasonable results, but still more deformation than you would expect in the field (approx. 20mm). The problem with adjusting the cohesion of the...

    Mimicking road surfaces in FD and FE models.

    I am trying to mimic a granular road surface, and apply a surface pressure representative of a live load vehicle (using FLAC and PLAXIS). The problem is, when the pressure is applied, the modeled surface experiences very large deformations. The Mohr Coulomb model I am using suggests that a...
