#1817 assigned defect

Exporting "Modelica.Electrical.Machines.Examples.AIMS_Start" to FMI generates invalid modelDescription.xml

Reported by: dh Owned by: Willi Braun
Priority: high Milestone: Future
Component: Code Generation Version:
Keywords: Cc:

Description

modelDescription.xml does not contain a valid min or starting attribute for ScalarVariable aims.airGapS.p

while simulation the model the default value is set to "2"

Exporting the example via Dymola 2013 resulsts in a correct behaivor

extract from modelDescription.xml

  <ScalarVariable
    name="aims.airGapS.p"
    valueReference="11"
    description="number of pole pairs"
    variability="parameter"
    causality="internal"
    alias="noAlias">
    <Integer/>
  </ScalarVariable>

The missing start/min value causes this error

division by zero in partial equation: (aims.airGapS.gamma - (-Real(aims.airGapS.p)) * aims.fixed.phi0) / Real(aims.airGapS.p) because Real(aims.airGapS.p) == 0

Seems to give bad initial conditions for the non-linear solver also for the regular code.

<Integer useStart="false" start="0" fixed="true" min="-2147483648" max="2147483647"   />

Milestone: 1.9.01.9.1

Postponed until 1.9.1

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

Milestone changed to 1.9.3 since 1.9.2 was released.

Milestone: 1.12.0Future

The milestone of this ticket has been reassigned to "Future".

If you think the issue is still valid and relevant for you, please select milestone 1.13.0 for back-end, code generation and run-time issues, or 2.0.0 for front-end issues.

If you are aware that the problem is no longer present, please select the milestone corresponding to the version of OMC you used to check that, and set the status to "worksforme".

In both cases, a short informative comment would be welcome.
