[TRNSYS-users] Solver 1 Error

[Krishna]

Hi David,
               The error with The Powell's method not working is occuring at Line 99 in Type109.f90

      do iunit=1,maxu+1        ! FIGURE OUT WHICH OF THE TYPE9 UNITS THIS IS
        if(unit(iunit) == info(1)) exit
      enddo
      if (iunit>maxu) goto 750 !ERROR

>From the code above it seems that the loop causing iunit to increase upto maxu+1. Then after the loop a check is performed to see if iunit>maxu which raises the error. I am not sure why this is not happening for solver 0.

Krishna

  Krishna,
    I have just done some testing and I do not find any problems running a SOLVER 1 simulation that contains Type109.  In looking at the Type109 code, it would appear that you can get Error139 if you exceed the maximum number of Type109 instances in a given simulation. By default you are able to have 10 instances of Type109. If you would like to send me the input file that is giving you trouble, I would be happy to take a look at it. You can email it and any accompanying data files to dbradley at engr.wisc.edu.
  Kind regards,
    David

    Could any one let me know if Type 109 weather data is compatible with Powell method (Solver 1). When I run the simulation the program crashes and I get the following error in the list file.

    ***** ERROR *****        TRNSYS ERROR # 139
     UNIT 109 TYPE 109 NOT FOUND IN PROGRAM MEMORY.

     This simulation runs fine with Solver 2.
    Thank you,
    Krishna
