Strange element positions RINGDEFINITION

I tried to run my simulation using the RINGDEFINITION and Sbend3D with OPAL/1.9.

Starting from the input file properly running with OPAL/1.6, I have

  • update the version number
  • replace DISTRIBUTION=FROMFILE with TYPE=FROMFILE

all the rest of the input file is unchanged.

I realized that there is a problem with the element position:

  • OPAL1.6 (correct)
OPAL> * Added OFFSET to Ring
OPAL> * Start position (-1547.1, 9.47297e-14, 0) normal (6.12303e-17, 1, 0), phi 6.12303e-17
OPAL> * End position (-1547.1, 1800, 0) normal (6.12303e-17, 1, 0)
OPAL> * Added MAPS to Ring
OPAL> * Start position (-1547.1, 1800, 0) normal (6.12303e-17, 1, 0), phi 6.12303e-17
OPAL> * End position (1297.51, 2642.61, 0) normal (0.544639, -0.838671, 0)
  • OPAL1.9
OPAL> * Added OFFSET to Ring
OPAL> * Start position (-1.5471e+06, 9.47297e-11, 0) normal (6.12303e-17, 1, 0), phi 6.12303e-17
OPAL> * End position (-1.5471e+06, 1800, 0) normal (6.12303e-17, 1, 0)
OPAL> * Added MAPS to Ring
OPAL> * Start position (-1.5471e+06, 1800, 0) normal (6.12303e-17, 1, 0), phi 6.12303e-17
OPAL> * End position (-1.54426e+06, 2642.61, 0) normal (0.544639, -0.838671, 0)

Are there modification also to RINGDEFINITION element between OPAL/1.6 and OPAL/1.9? I don't get any warning or error message.
