Missing fixed=false in Modelica.Electrical.EnergyStorages.Batteries.Components.Calculators.Cycles

[modelica-trac-importer]

Reported by pharman on 15 Oct 2012 16:27 UTC
In Modelica.Electrical.EnergyStorages.Batteries.Components.Calculators.Cycles the parameter integrator.y_start is set at initialisation, but doesn't have the attribute fixed=false set so as a parameter defaults to fixed=true.

Therefore the declaration:

  Modelica.Blocks.Continuous.Integrator integrator(y_start=cyclesini);

should be changed to:

  Modelica.Blocks.Continuous.Integrator integrator(y_start(fixed=false)=cyclesini);

Library is not going to be part of MSL 3.2.1 so rescheduling for possible inclusion in MSL 3.3

The pendantic model check of Dymola rises an error message for

Modelica.Blocks.Continuous.Integrator integrator(y_start(fixed=false)=cyclesini);

However, I do not quite understand the intention of your proposal. Do you want to explicitly overwrite the integrator initial condition?

[christiankral]

The library structure is designed for quite sophisticated applications. Therefore, the library should definitely be re-designed and simplified before integrating it into the MSL.
