4590	SimCode execution times scale as O(N^4) with large parameter arrays	Francesco Casella	somebody	"SimCode execution times to create linear, non-linear and system jacobian parts scale very badly with size, when large parameter arrays are defined in models. See:

(https://libraries.openmodelica.org/branches/master/ScalableTestSuite/ScalableTestSuite.html ScalableTestSuite), ScalableTestSuite.Elementary.ParameterArrays.ScaledExperiments.Table_N_XX_M_XX:

||=NxM=||=Time (s)=||
||  2500||  0.30||
||  5000||  0.89||
|| 10000||  4.02||
|| 20000|| 15.12||
|| 40000|| 259.00||

This makes absolutely no sense. The time spent creating the code for an array with N elements should be O(N)."	defect	closed	high	1.13.0	Backend		fixed
