Today I improved the Bode model in the MSL order to overcome some numerical and initialization problems. Now, please consider example {{{Modelica.Electrical.QuasiStationary.SinglePhase.Examples.SeriesBode}}} (on master): * The simulation example simulates with no obvious complaints * The complex inputs bode.u and bode.divisor look reasonable * The division of the two complex inputs, however, is incorrect (see attached file), i.e., {{{divison.y.re = division.y.im = 0}}} ... the results shall NOT be zero I do not understand where this comes from, as the simple test example {{{#!mo model TestComplexDivision Modelica.ComplexBlocks.Sources.ComplexConstant complexConst1(k = Complex(1, 1)) annotation( Placement(visible = true, transformation(origin = {-70, 10}, extent = {{-10, -10}, {10, 10}}, rotation = 0))); Modelica.ComplexBlocks.Sources.ComplexConstant complexConst(k = Complex(2, 3)) annotation( Placement(visible = true, transformation(origin = {-70, -30}, extent = {{-10, -10}, {10, 10}}, rotation = 0))); Modelica.ComplexBlocks.ComplexMath.Division division1 annotation( Placement(visible = true, transformation(origin = {-30, -10}, extent = {{-10, -10}, {10, 10}}, rotation = 0))); equation connect(complexConst.y, division1.u2) annotation( Line(points = {{-58, -30}, {-50, -30}, {-50, -16}, {-42, -16}, {-42, -16}}, color = {85, 170, 255})); connect(complexConst1.y, division1.u1) annotation( Line(points = {{-58, 10}, {-50, 10}, {-50, -4}, {-42, -4}, {-42, -4}}, color = {85, 170, 255})); end TestComplexDivision; }}} works OK and the division1.y shows the correct result. So {{{TestComplexDivision}}} works OK, but {{{Modelica.Electrical.QuasiStationary.SinglePhase.Examples.SeriesBode}}} does not work. This issue applies to {{{ OMEdit 1.13.0~dev-106-g36aa34a Connected to OpenModelica 1.13.0~dev-729-gdbcd957 }}} on a 64bit Linux machine.
