initialization and dynamic state selection

[Volker Waurich]

Hi,
The model ComparisonQuasiStationary2 in testsuite\simulation\modelica\resolveLoops fails at initialization with the error:

Error: Model error. 0^(-2) is not defined

This comes from the jacobian of the linear system:

{6,3}:simpleSolenoid2_1.g_mFePole.G_m ^ -2.0,

It should not be initialized with zero. I think this has something to do with dynamic state selection. Could you please check if the start values are computed or initialized with default 0 if there is a stateSet?

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

Initialization of DSS should be fixed in the meanwhile. Unfortunately, I cannot test this particular example, since the symbolic jacobians break compilation:

ComparisonQuasiStationary2_03lsy.c: In function ‘ComparisonQuasiStationary2_initialLinearSystem’:
ComparisonQuasiStationary2_03lsy.c:347: error: ‘ComparisonQuasiStationary2_functionJacNLSJac2_column’ undeclared (first use in this function)
ComparisonQuasiStationary2_03lsy.c:347: error: (Each undeclared identifier is reported only once
ComparisonQuasiStationary2_03lsy.c:347: error: for each function it appears in.)

(see #3127)
