1083	[MSL] [Machines] Differentiation of Abs not supported: AIMC_Inverter (from MathCore)	krsta	krsta	"(Old MathCore Track ID 1144)

Initiation of ""Modelica.Electrical.Machines.Examples.AIMC_Inverter"" as experiment ""Modelica.Electrical.Machines.Examples.AIMC_Inverter 1"" started at 17:36:40
ERROR: Building of model failed. Kernel error.
The language feature differentiation of function abs is not supported. Suggested workaroung: no suggestion

The problem is derivation when reducing index. A simple test is this model provided py Peter:
{{{
model abstest 
  Real x;
  Real y;
equation 
  der(x)+der(y)=2;
  x+abs(y)=0; // Denna ekvation måste deriveras vid indexreduktionen
end abstest;
