## Abaqus Cards

Loads or constraints that are to be used as history data (under *STEP) should be collected into load collectors with the HISTORY card image. These load collectors also need to be added to the corresponding load steps (*STEP). In contrast, loads or constraints for model data should be collected into load collectors with INITIAL_CONDITION card image. They will automatically be written out in the model portion of the Abaqus input deck.
Note: All loads and boundary conditions on sets can be expanded to individual nodes and elements by selecting the Expand load on sets option in the File Options dialog, which is invoked upon importing a solver deck. If a **HMLOAD_SETS_EXPAND comment is found in the input file, all loads and boundary conditions on sets are expanded to individual nodes and elements.

Load collector information is specified with a required $HMNAME comment card and an optional$HMCOLOR comment card. If an input translator encounters one of these comments while reading a load card, a new load collector is created. For the comments to be valid, they must follow a load keyword or the last line of the previous Structured block. The loads that follow a $HMNAME LOADCOLS comment are read into that collector. If there is a new keyword or structured block, the previous load collector information is ignored. For non-HyperMesh generated input decks, loads are divided into collectors based on classification. The following load collectors are created: • Mechanical loads for forces and moments • Constraints/Displacements • Velocities • Accelerations • Pressures If translational or rotational constraints are defined in the input model, they are placed in a separate load collector named Nodal Constraints. Load collectors are not used by LS-DYNA, but are useful for visualization. Additional load collectors can be defined to describe other entities.

Specific load collectors have a card image which can be edited to group other load collectors together for simultaneous application in a single subcase, or to provide special information for a specific analysis type, such as modal analysis. Use specific load collectors for specialized loading cards, such as SPCADD, MPCADD, EIGRL, EIGB, EIGC, EIGP, EIGR, FREQ, FREQ1, LOAD, GRAV, RFORCE, and TEMPD. Generic load collectors do not have a card image. Use generic load collectors to collect loads and constraints for display purposes and to assign an ID to the loads. General boundary conditions, such as loads and constraints, should not be collected into specific load collectors. Organizing loads and constraints into a specific load collector may result in an error termination. When a Nastran deck is imported into HyperMesh, loads that have the same SID are collected into the same load collector. If a load collector already exists in the database with the same SID, one of the following can occur: • If overwrite is off (default), the new load collector’s ID is offset and all loads in that collector will have a new SID upon export. • If overwrite is on, the new load collector replaces the existing load collector. The original load collector and the loads it contains are deleted. Card Description ACSRCE Defines the power versus frequency curve for a simple acoustic source.

$CONTVAL Assignment of properties to contacts referenced by contact identifier or name. Note: Supported as a load collector (card image LOADS). To create a card, use an existing load collector or create a new one with card image LOADS and select the CONTVAL check box. A maximum number of 5 keywords are allowed per load collector (load pattern).$PRETENSION LOAD Assignment of load properties to pretension threads/areas referenced by identifier or name.
