#4184 closed defect (duplicate)

Display unit "deg" converted wrong on windows

Reported by: dma@… Owned by: Lennart Ochel
Priority: critical Milestone: 1.12.0
Component: Run-time Version: v1.12.0

Description

I am getting an incorrect simulation result from recent nightly builds of OpenModelica-64bit.

File Motor1Da-v1.11.0-dev-93-gaadd604.png shows what I believe is a correct result. The file Motor1Da-JModelica.png shows the result of simulating the same system using JModelica, with results that agree with the OM v1.11.0-dev-93 result.

File Motor1Da-v1.12.0-dev-54-gc3e6c1b.png, however, shows a different result and one that does not make any sense. The relevant equation from the inertial element is, w = der(phi);, which is directly contradicted by the result which has phi as negative and w as positive.

I have also attached the source file used for all of these simulation, Motor1Da.mo.

This model works for me as expected. Can anybody run it on windows?

Summary: Incorrect simulation result → Display unit "deg" converted wrong on windows

Okay, the simulation results are correct even on windows. This is an issue of display unit "deg" on windows, it seems to work correct on a linux machine.

Seems like a duplicate of #4125.
