Python TransformToPlane Examples

Example #1

File: band_gaps_conf.py Project: zitkat/sfepy

def get_pars(dim, lam, mu):
    c = stiffness_from_lame(3, lam, mu)
    if dim == 2:
        tr = TransformToPlane()
        try:
            c = tr.tensor_plane_stress(c3=c)
        except:
            sym = (dim + 1) * dim // 2
            c = nm.zeros((sym, sym), dtype=nm.float64)

    return c
