SysML parameter names are replaced in the Modelica equations according to the bindings in Figure 13 [ERROR]: f is replaced by u, pos is replaced by y, x is replaced by position, k is replaced by springcst, v is replaced by velocity, m is replaced by mass.

SysML parameter names are replaced in the Modelica equations according to the bindings in Figure 13: f is replaced by u, pos is replaced by y, x is replaced by position, k is replaced by springcst, v is replaced by velocity, m is replaced by mass.


model Spring
  input Real u;
  output Real y;
  Real position;
  parameter Real springcst = 1;
  Real velocity;
  parameter Real mass = 10;
equations
  der(velocity)=(u-springcst*position)/m;
  der(position)=velocity;
  y=position;
end Spring;

Next snippet

There is an error in the Figure reference:

The reference to 'Figure 13' is wrong

There are two errors in the Modelica code:

The keyword equation not equations should be used

It should probably say SpringMassSys not Spring
