•	FX: force in direction X

•	FY: force in direction Y

•	FZ: force in direction Z

•	MX: moment in direction X

•	MY: moment in direction Y

•	MZ: moment in direction Z

•	RX: rotation in direction X

•	RY: rotation in direction Y

•	RZ: rotation in direction Z

•	FXI: force in direction X (see Comment 2)

•	FYI: force in direction Y (see Comment 2)

•	FZI: force in direction Z (see Comment 2)

•	MXI: moment in direction X (see Comment 2)

•	MYI: moment in direction Y (see Comment 2)

•	MZI: moment in direction Z (see Comment 2)

Adding to this, the following variables are available in HyperGraph (HG):

•	TF: magnitude of force (computed in HG as (FX2 + FY2 + FZ2)1/2)

•	TM: magnitude of moment (computed in HG as (MX2 + MY2 + MZ2)1/2)

•	R: magnitude of rotation (computed in HG as (RX2 + RY2 + RZ2)1/2)

•	FI: magnitude of force (computed in HG as (FXI2 + FYI2 + FZI2)1/2)

•	MI: magnitude of moment (computed in HG as (MXI2 + MYI2 + MZI2)1/2)

Warning:

Additional variables are computed correctly only if requested variables for computation are saved in TH. For instance, TF is computed correctly only if FX, FY, or FZ are requested to be saved by you.

1.	Available names are listed in the two tables above.

In the first table, TH-variables are listed. If a TH-variable is requested, this variable is written.

In the second table, other variable groups are listed. If a variable group is requested, all the associated TH-variables are written at once.

2.	FI, MI, FXI, FYI, FZI, MXI, MYI, and MZI are the forces applied by interfaces type 14 or 15 on the envelope surface (if available).
