THIS FUNCTION EXTRACTS THE FRINGE VARIABLES FROM D3PLOTS AND RETURNS THEM IN A 3D COMPACT FORM THAT CAN BE VIEWED IN A WEB BROWSER¶
Extracts fringe variables (e.g. von Mises stress, effective plastic strain, triaxiality, displacement) from LS-DYNA d3plot binary databases and converts them into a compact JS3D file for interactive 3D visualization in a web browser. Use this worker to generate browser-viewable 3D contour/fringe animations directly from d3plot results.
When to use¶
Classification: process.
Tagged: 3d_visualization, contour, d3plot, displacement, eps, fringe, js3d, ls-dyna.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| File Name | filename | string | d3plot | Base name of the d3plot file to read (default: ‘d3plot’); used with the File Condition to locate the correct result file on disk. | |
| File Condition | file_condition | string | eq | String-matching rule applied to the file name when searching for d3plot files; options are ‘eq’ (exact match, default), ‘starts_with’, ‘ends_with’, or ‘anywhere’. | |
| Output Filename Name | outputfilenamename | string | output.js3d | Name of the output JS3D file that will be written (default: ‘output.js3d’); must include the .js3d extension. | |
| First State | first_state | scalar | 1 | Integer index of the first d3plot state (time step) to include in the extraction (default: 1, i.e. the first available state). | |
| Last State | last_state | scalar | 9999 | Integer index of the last d3plot state to include; set to a large sentinel value (default: 9999) to capture all available states. | |
| Increment | increment | scalar | 1 | Step increment between extracted states (default: 1); increase to sub-sample states and reduce output file size. | |
| Fringe Variables | fringe_variables | scalar | eps | Fringe quantity to embed in the JS3D file; choose from ‘vm’ (von Mises stress), ‘eps’ (effective plastic strain, default), ‘triaxiality’, or ‘disp’ (resultant displacement). | |

Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| js3d_write_file_output_1 | js3d_write_file_output_1 | view | Browser-renderable JS3D view file containing the extracted 3D fringe contour data for all requested states; open directly in d3VIEW’s web 3D viewer. |
