MoCustomComponent block

Minoru Yubuchi_21420

Dear Experts,

 

I built a simple model that contains a MoCustomComponent block that represent a mass (see attached Activate model). The script in the block is just copied from Mass modelica block.

 

The model issued the error (see the picture attched). What should I modify?

 

Thanks,

Minoru Yubuchi

Hello Minoru,

 

Your modelica Code should be something like that:

 

model C_Mass 'Sliding mass with inertia'
    parameter Modelica.SIunits.Mass m(min = 0, start = 1) 'Mass of the sliding mass';

    extends Modelica.Mechanics.Translational.Interfaces.PartialRigid(L = 0, s(start = 0));

    Modelica.SIunits.Velocity v(start = 0) 'Absolute velocity of component';
    Modelica.SIunits.Acceleration a(start = 0) 'Absolute acceleration of component';
equation
    m * a = flange_a.f + flange_b.f;
    a = der(v);
    v = der(s);
end C_Mass;

 

Note that I've removed the stateselect since it is not a block parameter, you can put it back if needed.

 

Thanks
