Badly displayed transformer model

Reported by: massimo ceraolo Owned by: Adeel Asghar
Priority: high Milestone: 1.13.0
Component: OMEdit Version:
Keywords: Cc:

Description

The MSL model Electrical.Analog.Basic.Transformer is badly displayed by OMEdit: the connectors are placed far from the related wires.

I did not check the code to verify whether this is an OM or MSL issue.
However since the transformer model has been in the MSL for years, I suspect that this is a OM issue.

Note that Dymola shows the transformer correctly.

Tested with OM v1.13.0-dev-380-g8b177b9 (WIN-64-bit)

OpenModelica is using the latest MSL and seems like Dymola is using a bit older.

See the difference between the annotations of PositivePin and NegativePin. It is MSL issue so you need to open a ticket on Modelica trac or github.

I just opened ticket #2456 on github.

comment:3 by massimo ceraolo, 7 years ago

Ehm...
Indeed the issue has been solved in a perfect way in Modelica trunk.
I've already closed ticket #2456 on github.
