All the units must be on International System of Units (SI) . Keyboard Options: [Esc]  exit [r]  restore initial object shape [<] or [>] or [,] or [.]  rotate object in real space Visualization [arrows]  rotate object [s] and [S]  change the object size [p] and [P]  change the object z position [F1]  normal [F2]  wire frame [F3]  fibers connecting a vertex (green) and the vertex force (yellow). Pressing again change vertex [F4]  all vector vertex area (white) [F5]  vector face area (blue) and vector vertex area (white). Pressing again change vertex [F6]  neighbor vertices (green), surface tension (yellow) and vertex area (white) [F7]  all the existing fibers [F8]  all the fibers turned off DOS window [b]  choose border conditions [y]  choose new Young Modulus Gravity [i]  change gravity variation for each iteraction in m/s2 and the number of iteraction in each step (for example: if gravity variation = 2 and number of interaction = 3 the variation of gravity is 6 m/s2) [g] and [G]  apply or remove one gravity step with CONSTANT matrix [a] and [A]  apply or remove one gravity step with VARIABLE matrix Paddles [=]  compression by a pair of paddles (VARIABLE matrix) [ or ]  compression by a one paddle (VARIABLE matrix) Move the probe [Home] and [End]  horizontal (VARIABLE matrix) [PgUp] and [PgDn]  vertical (VARIABLE matrix) [m] and [M]  position (CONSTANT matrix) [j] and [h]  horizontal (CONSTANT matrix) [u] and [n]  vertical (CONSTANT matrix) ON/OFF [l]  stress strain linear/nonlinear (VARIABLE matrix) [f]  area of vector B variable/constant (CONSTANT matrix) [c]  fibers connections that pass out of the object are turned off/on (VARIABLE matrix)
