RE: Question about type 81 (Borehole model (Dr. P. Pahud)

[Michaël Kummert <kummert@xxxxxxxxxxxxxxx>]

Maurice,

A range Check error indicates that a routine (most probably Type 81 in your
case) is trying to access an element that does not exist in an array. This
would occur, for example, if you try to access element "0" of an array, or
if you try to access MyArray[11] if MyArray was declared sith a size.

If you have a Fortran compiler (I assume you do since you are using a
non-standard Type), you should be able to figure out the cause of the error
easily.

Make sure that:
- You are in Debug mode
- You tell the compiler to check for this type of errors
  In CVF66A:
  Go to Projects/Settings/Fortran
  Select RunTime in pull-down menu
  Check "Array and Strings bounds" under "Runtime Error Checking"
- You stop at the error.
  In CVF66A:
  Insert a breakpoint at the very beginning of the simulation
  When the debugger stops there, go to "Debug/Exceptions"
  Choose "Stop Always" for all possible exceptions

If you run Trnsys in Debug mode, it should show you the line where the range
check error occurs.
If you don't want to use the debugger, you can use trial and error to find
which parameter causes the problem.

Michaël Kummert
