Getting y matrix through conet crashes pss e

I am using this api CALL OUTPUTYMATRIX in the conet subrutine , i need it for printing the ybus elements in the progress window , before running a simulation i use this code, but pss e crashes , i want to know if its possible to use this api during dynamic simulation in a user model for example

 SUBROUTINE CONET

  INCLUDE 'COMON4.INS'

  IF (.NOT. IFLAG) GO TO 9000

   WHEN (MODE.EQ.1 .OR. KPAUSE.EQ.2)
  . 
  .  CALL OUTPUT_Y_MATRIX(0,1,1,0, 'x.txt', 0)
  ...FIN
  ELSE RETURN

  9000 CONTINUE
  RETURN
  END

The last argument in the subroutine call should be an integer variable, e.g. IERR. You have entered a constant.

Isn't it easier to just call the python API before the first run command, instead of calling it in Fortran from CONET?

@perolofl thanks , i want to do this with the conet subroutine in fortran because i want to know if it is possible to get the data of the admittance matrix during a dynamic simulation through an user model, i need some values of the Ybus so i want to know if its possible to do this

Does it work after changing to IERR?

no , still crashes pss e , i used 0 as the IERR code , but anyway cant do the initialize activity because it just stops working

Can you show the call statement you are using?

im using this code in CONET, then create dll gui and the cload4 command , i call the ymatrix output in mode 1 because i think i will print the ybus in the initialization strt WHEN (MODE.EQ.1) . . CALL OUTPUT_Y_MATRIX(0,1,1,1, 'OFILE.txt',0) ...FIN ELSE RETUN

I agree that Python is the easier way to get what you want.

The following is a lot more work, but it might be a preferred option for you, if you want to avoid writing/using Python code for every simulation. You could also consider writing a CCT model instead of a CONEC model. This is a v33+ feature. This type of model can be written as a DLL with the functionality that you want, and unlike a CONEC model it does not have to be compiled at run time. I'd advise you to get your CONEC code working correctly before you try to convert it to a CCT model.

Happy coding!

thanks a lot for the suggestion, i am currently using the version 32 of PSSE so for me its not possible use a cct model type , i want to know tho if its possible to get the values of the Ybus during dynamic simulation through an user model , do you know if its possible??

It should be possible to get the Ybus through a user model, but you will have to write, test and debug this model to get it working (whether you write it as a CONEC model or something else). That seems like a lot of work when you can achieve the same objective using Python coding.
