Python CSCart.setSpaceDim Beispiele

Beispiel #1

# (negative, y is negative)
tractions_bg_normal = density*gacc*(vertices[:,1])

# Background shear tractions are reverse (in 2-D right-lateral is negative)
# because the normal tractions are negative.
tractions_bg_shear = coef_friction*tractions_bg_normal

# Combine traction changes and background tractions
tractions_shear = tractions_bg_shear + tractions_change[:,0]
tractions_normal = tractions_bg_normal + tractions_change[:,1]
