MATERIAL SPECIMEN GENERATOR FOR SOLID CUBE¶
Generates a solid cube material specimen (LS-DYNA keyword deck) for uniaxial material calibration tests. The user selects cube side length, mesh size, element formulation, and loading parameters to produce a ready-to-run single-element or multi-element solid cube coupon. Use this worker to quickly set up a cube specimen simulation for material characterization or calibration workflows.
When to use¶
Classification: data.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Type | length | string | 1in | Side length of the solid cube specimen (default: ‘1in’); currently only ‘1in’ is available — leave as default unless additional sizes are added. | |
| Type | meshsize | string | 5mm | Target element edge length for meshing the cube (options: ‘2mm’ or ‘5mm’; default: ‘5mm’) — choose ‘2mm’ for a finer mesh or ‘5mm’ for a coarser, faster-running single-element approximation. | |
| Elform | elform | scalar | -1 | LS-DYNA element formulation integer for the solid elements (default: -1, fully-integrated selective-reduced solid); refer to LS-DYNA manual for other ELFORM values. | |
| Mass-Scaled Time Step | mass-scaled_time_step | scalar | 0 | Target time step for mass scaling in seconds (default: 0 disables mass scaling); set a positive value to enable DT2MS mass scaling in the LS-DYNA deck. | |
| V-A-D | velocity-acceleration-displacement | scalar | 2 | VAD flag controlling whether the prescribed load curve is interpreted as velocity (0), acceleration (1), or displacement (2) in *BOUNDARY_PRESCRIBED_MOTION (default: 2 = displacement). | |
| Loading Input | loading_input_type | scalar | constant | Determines whether the applied loading is a constant value (‘constant’) or follows a user-supplied curve (‘curve’); default is ‘constant’. | |
| Displacement Or Velocity Or Acceleration Value | displacementor_velocityor_acceleration_value | scalar | 25 | Displacement Final value | |
| Duration | duration | scalar | 100 | CONTROL_TERMINATION | |
| Binary Output Frequency | binary_output_frequency | scalar | 1 | ||
| ASCII Output Frequency | ascii_output_frequency | scalar | 0.1 | ||
| Material ID | material_i_d | scalar | — | ||
| Material Data | material_data | text | — | Material Card | |
| IRATE | irat_e | scalar | 0 | ||
| IMFLAG | imfla_g | scalar | 0 | ||
| IMASS | imas_s | scalar | 0 | ||
| DT0 | d_t0 | scalar | 0.1 | ||
| ILIMIT | ilimi_t | scalar | 10 | ||
| MAXREF | maxre_f | scalar | 15 | ||
| IACC | iac_c | list | 0 | ||
| Additional Keywords | additionalkeywords | text | — | Add additional keywords (Optional) | |
| Element Type | elementtype | scalar | hexahedron | Type of element used for discretization |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| material_specimen_generator_cube_solid_output_1 | material_specimen_generator_cube_solid_output_1 | text | LS-DYNA keyword input deck (plain text / .k file) defining the solid cube specimen geometry, mesh, boundary conditions, and loading — ready for solver submission or downstream material calibration workers. |
