MASS |
Units of mass. See comments 1 and 7. Default = KG (KG, LBM, SLUG, GRAM, OZM, KLBM, MGG, SLINCH, UG, NG, USTON, or MG) |
FORCE |
Units of force. See comments 2 and 7. Default = N (N, LBF, KGF, OZF, DYNE, KN, KLBF, MN, UN, or NN) |
LENGTH |
Units of length. See comments 3 and 7. Default = MM (MM, KM, M, CM, MI, FT, IN, UM, NM, ANG, YD, MIL, or UIN) |
TIME |
Units of time. See comments 4 and 7. Default = S (S, H, MIN, MS, US, NANOSEC, or D) |

| 5. | PARAM, WTMASS is ignored for the multi-body and component mode synthesis (flexible-body preparation) solution sequences. Unit data for these solution sequences is supplied on the DTI,UNITS bulk data entry. |
| 6. | This DTI, UNITS data entry is the same as the UNITS entry. |
| 7. | If the units defined on the DTI,UNITS entry are not consistent, mass unit is ignored, only force, length, and time units are considered in Geometric Nonlinear Analysis (ANALYSIS = EXPDYN) subcases. |
| 8. | This card is represented as a control card in HyperMesh. |
