DLOAD – Dynamic Load Combination or Superposition
Description
Defines a dynamic loading condition for frequency response problems as a linear combination of load sets defined via RLOAD1 and RLOAD2 entries, or for transient problems as a linear combination of load sets defined via TLOAD1 and TLOAD2 entries, or acoustic source ACSRCE entries.

SID |
Load set identification number. No default (Integer > 0) |

Scale factor. No default (Real) |
S# |

L# |
Load set identification numbers of RLOAD1 and RLOAD2 or TLOAD1 and TLOAD2, or ACSRCE Bulk Data Entries. No default (Integer > 0) |
| 1. | Dynamic load sets must be selected in the I/O Options or Subcase Information sections with DLOAD=SID. (See I/O Options and Subcase Information DLOAD entry). |
| 2. | The load vector being defined by this entry is given by: |
| 3. | Each L# must be unique from any other L# on the same entry. |
| 4. | SID must be unique from all RLOAD1 and RLOAD2 or TLOAD1 and TLOAD2 entries. |
| 5. | A DLOAD entry may not reference a set identification number defined by another DLOAD entry. |
| 6. | RLOAD1 and RLOAD2 loads and TLOAD1 and TLOAD2 loads may be combined only through the use of the DLOAD entry. |
| 7. | This card is represented as a loadcollector in HyperMesh. |
