Issues Descriptions

modelica port does not export special characters

  • Key: SYSPHS11-1
  • Status: closed  
  • Source: Pratt and Whitney ( Jay Lamphier)
  • Summary:

    I am trying to specify block connection through the modelica port interface and the port I am attempting to connect to within my library is named ports[1]. Upon exporting the SysMl code I am not able to generate the desired modelica text, resulting in the following code: connect(name.ports1,name2.port). Where name.ports1 is explicitly defined in the proxy port specification with the applied stereotype of ModelicaPort and ProxyPort with the tag name ports[1].

    SYSPHS11-1 close

    Our guess is the implementation the filer is using removes square brackets from port names because those are reserved notation in Modelica. The specification could require translation to remove platform special characters (or replace them with a non-special character) from SysML names, but these characters might differ between platforms and causes naming conflicts on translation.

Explain how to identify source of errors in (debug) physical interaction models

  • Key: SYSPHS11-3
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    Physical interaction is bidirectional, making it difficult to predict how a model will simulate, or to find the source of unintended simulation results (debug).

Add example combining physical interaction and signal flow

  • Key: SYSPHS11-2
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    The current examples are of physical interaction or signal flow separately (the humidifier example has signals carrying physical information, but doesn't use physical interaction).

    See revised text. Include file SysPhSAnnexA-CruiseControl.xmi among the non-normative artifacts (see zip file in resolution to SYSPHS11-6).

Electrical component behavior library missing units

Physical interaction library XMI missing InterfaceBlock stereotype applications

  • Key: SYSPHS11-9
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    In SysPhSLibrary.xmi, the elements corresponding to the *FlowElement interface blocks in Figure 31 (Elements for physical interaction) have Block applied instead of InterfaceBlock.

  • Disposition: Duplicate or Merged — SysPhS 1.1
  • Disposition Summary:

    SYSPHS11-9 merge

    In SysPhSLibrary.xmi, in stereotype applications to elements with names ending in "FlowElement", replace "Block" with "InterfaceBlock", and update the corresponding xmi:id (see SysPhSLibrary.xmi in resolution to SYSPHS11-6).
