# NLOAD

Bulk Data Entry Defines a loading condition for nonlinear problems as a linear combination of load sets defined via NLOAD1.

## Definitions

Field Contents SI Unit Example
SID Load set identification number. SID must be unique from all NLOAD1 entries.

No default (Integer > 0)

S Scale factor.

No default (Real)

Si Scale factors.

No default (Real)

Li Load set identification numbers of NLOAD1. Each Li must be unique from any other Li on the same entry.

No default (Integer > 0)

## Comments

1. Dynamic load sets must be selected in the I/O Options or Subcase Information sections with NLOAD=SID.
2. The load vector being defined by this entry is given by:(1)
$\left\{P\right\}=S\sum _{i}\mathit{Si}\left\{{P}_{i}\right\}$
3. An NLOAD entry may not reference a set identification number defined by another NLOAD entry.
4. This card is represented as a load collector in HyperMesh.
