Field transform files, *.FLT

The field transform files contain the definitions of all components all field transformations using the MaX-1 formula interpreter language as well as PFD information. These files are only created by the MaX-1 software. OpenMaXwell can read these files for compatibility reasons, but it will ignore the the formulae defining field transforms because the corresponding GFD solver is not contained in OpenMaXwell.

Data structure:

• File ID string (Current version: " CHFLT Version 2.0")

• Constant time step, compute abbreviations once, leap frog, use predefined operator (4 integer values: 0:no, 1:yes)

• Number of iterations (1 integer value)

• Time step (1 real value)

• Real constants c6,c7,c8 (3 real values)

• Dummy text (1 character string)

• LOOP i=1,20

•     Abbreviations (1 character string)

• LOOP i=0,6 (internal, left, right, bottom, top, rear, front)

•     Dummy text (1 character string)
