```rust
dot_product(&frc_t0_trb, &m.coord_sys.a2) * 1000.0;
```

`m.coord_sys.a2`  --- Z

`frc_t0_trb` Total force at the base of flexible portion of the tower (point T(0)) due to the entire wind turbine

`PFrcT0Trb`      Partial force at the tower base (point T(0)) due to the turbine 
`PMomX0Trb`      Partial moment at the platform (body X) / tower base (point T(0)) due to the turbine
`FrcT0Trbt`      Portion of the force at tower base (point T(0)) due to the turbine associated with everything but the QD2T()'s
`MomX0Trbt`      Portion of the moment at the platform (body X) / tower base (point T(0)) due to the turbine associated with everything but the QD2T()'s
