Masses

When performing a dynamic analysis, the mass of the structure has to be specified.

Point mass

This is a mass applied to one point of the structure. Default units are kilogram for the translation mass components and kilogram by square meter for the rotation mass components.

Beam mass

A beam mass is specified when considering the distributed mass of a beam.

Default units are kilogram/meter for translation mass and kilogram.meter for rotational mass.

Face shell mass

This is a mass applied to a side of a shell element of the structure.

Default units are kilogram/meter for translation mass and kilogram.meter for rotational mass.

Surface shell mass

This is a mass applied to a shell element of the structure.

Default units are kilogram/ square meters.
