   * gravitational acceleration (''opt.gravity''): default unit is m/s^2 so acceleration scales as 1/L.   * gravitational acceleration (''opt.gravity''): default unit is m/s^2 so acceleration scales as 1/L.
  
-In other words, if your script assumes meters as the unit for length, and you want to go to millimeters, the ''nodes'' matrix should be multiplied by 10^3. Likewise, the forces should be multiplied by 10^3, the moments by 10^6, the elasticity and shear modulus by 10^(-6), and all other quantities according to the list above.+In other words, if your script assumes meters as the unit for length, and you want to go to millimeters, the ''nodes'' matrix should be multiplied by 10^3.
