PARAM, WTMASS

Bulk Data Entry Converts weights to masses using this multiplier.

Parameter Values Description
WTMASS < Real > 0.0 >

Default = 1.0

 The WTMASS (Weight-To-MASS) parameter is used as a multiplier for the terms of the structural mass matrix.

Comments

  1. This parameter only applies to structural elements. It does not apply to either fluid elements nor MFLUID.
  2. This parameter cannot be applied to superelements (.h3d or .pch) that are read into the model. If the unit of mass is incorrect on the MAT# entries and PARAM, WTMASS is required to update the structural mass matrix, then this should be done in the creation run.
