Compile large array in Dymola

Question

Please consider the following small Modelica model and function:

model VectorizeDemo
  parameter Integer na=5;
  final parameter Integer nb=2*na;
  final par         


        

Answer 1

IIRC, some parts of the Modelica specification are written in a way that requires scalarization of all variables. That is not necessary for many cases, but simpler for some common cases in index reduction. It seems particularly unnecessary for some cases of discretized PDE.
