Linearization of CombiTable2D fails

[hans.hell@…]

in version v1.9.4-dev.beta1.116+gdd6bae1

obviously CombiTable2D is not considered in Linearization.
therefore result in matrix B is not correct
see attached example.

[hans.hell@…]

Correction: I attached wrong *.mo (table.y == 3.0) --> this cannot work.

In the NEW LinTabNEW.mo with a table ( y =u1+u2 ) should give a linearized system with B !=0.0
sorry for the inconvenience.

Milestone pushed to 1.9.5

Milestone renamed

[hans.hell@…]

in the current version the C-source for derivative calculation is missing! See example below.

modelica_real omc_$DER$$PModelica$PBlocks$PTables$PCombiTable2D$TAB$PgetTableValue(...)
{
  modelica_real _$$PModelica$PBlocks$PTables$PCombiTable2D$TAB$PgetTableValue$funDERy;
  modelica_real _y;
  _tailrecursive: OMC_LABEL_UNUSED
  _return: OMC_LABEL_UNUSED
//
// RETURN never defined
//
  return _$$PModelica$PBlocks$PTables$PCombiTable2D$TAB$PgetTableValue$funDERy;
}

Problem can be solved by manual C-coding of the derivative function (similar to the getTableValue-function). Then the derived A,B matrices are correct.

If you think getTableValue should have a derivative function, you should open a bug report on ​modelica.org

Ticket retargeted after milestone closed

[Martin Sjölund]

Milestone moved to 1.12.0 due to 1.11.0 already being released.

[Willi Braun]

The derivative functions is missing due to the fact that functions were removed with the module removedUnusedFunction, which is applied to early.
This should be fixed with ​OMCompiler#1665.
