Error messages in System Modeler when running examples

Posted 13 days ago

Hi There,

I'm completely new to system modeler. I have installed version 14 and get errors when I try to run some of the examples (in life sciences and aircraft). Any suggestions on fixing this.

Error: Aircraft.Physical.AuxiliaryObjects.TowingRope [38:3-38:3] Element not found. When looking up Modelica.SIunits.Force in scope Aircraft.Physical.AuxiliaryObjects.TowingRope, SIunits was not found in Modelica.
Error: Aircraft.Examples.GliderTow [4:3-4:3] Element not found. When looking up Modelica.Mechanics.MultiBody.Visualizers.Ground in scope Aircraft.Examples.GliderTow, Ground was not found in Modelica.Mechanics.MultiBody.Visualizers. Error: Aircraft [2:3-2:3] Element not found. When looking up .Modelica.SIunits in scope Aircraft, SIunits was not found in Modelica.
Error: IndustryExamples.LifeSciences.Chromatography.Components.LactoseBreakdown [6:7-6:7] Element not found.

Many thanks for that. Looking forward to playing with SystemModeler.

In System Modeler 14.0 the default version of Modelica Standard Library (MSL) was changed to 4.0.0. The current release of Aircraft library requires MSL 3.2.3, so you need to change the MSL version (right click on Modelica in the class browser and select Version > 3.2.3.

The IndustryExamples.LifeSciences.Chromatography.ChromatographySeparation example requires the BioChem library (as stated in the documentation when you open it), you can get it here https://www.wolfram.com/system-modeler/libraries/biochem/.
