Variable
icc2
Connection coefficients of the second kind. In itensor
, defined as
c c c c icc2 = ichr2 - ikt2 - inmc2 ab ab ab ab
In this expression, if iframe_flag
is true, the Christoffel-symbol
ichr2
is replaced with the frame connection coefficient ifc2
.
If itorsion_flag
is false
, ikt2
will be omitted. It is also omitted if a frame base is used, as the
torsion is already calculated as part of the frame bracket.
Lastly, of inonmet_flag
is false
,
inmc2
will not be present.
