# 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.
