Comments
- The syntax /H3D/ELEM/Keyword3/Keyword4/Keyword5 is also valid.
- When PART IDs are listed after the /H3D/QUAD line the specified results will only be output for those parts.
- To request integration point results, use /IR=i/IS=j notation where the options can be entered in any order.
- For failure criteria using different modes (mainly for composites), such as /FAIL/HASHIN, /FAIL/CHANG, and so on, these different modes can be output using the /H3D/QUAD/FAILURE option with the keyword MODE. You can choose to plot a specific mode using its number I (refer to the failure criterion documentation for mode number details), or all modes with ALL.
