# PRESSURE TEST - SOLID ELEMENTS
#
# Problem Description
# A pressure load is applied to a block of dimensions 1m x 1m x 1m.
# The load is applied at time 0 and then held constant for the rest of
# the time.
#
# Model Description
# The block is modelled using a single Solid_Iso_6 element. Pressure is
# applied at one side through the use of distributed node loads.
#
# Engineering Data
#  Mass of block          =  1000 kg
#  Center of gravity      = (0.5,0.5,0.5)
#  Ixx = Iyy = Izz        = 250 kgm2
#  ixy = Iyz = Izx        = 0
#  timestep               = 0.005 seconds
#
# Reference results
#  Total force of block   = 1.0 N
#  Acceleration of block  = 0.001 m/s2
#
# Comparisons of results
# The block shows a linear increase in velocity to 0.001 m/s in
# one second. This agrees with theory.
