# Description
3D Element Stress result values
Note: This is a dropdown component and input/output may vary depending on the selected dropdown
# Input parameters
 | Result List | Result | Result |
 | List | Element filter list | Filter the Elements by list. (by default 'all') Element list should take the form: 1 11 to 20 step 2 P1 not (G1 to G6 step 3) P11 not (PA PB1 PS2 PM3 PA4 M1) Refer to help file for definition of lists and full vocabulary. |
# Output parameters
 | Unit Number Pressure Tree | Stress XX | * Stress in XX-direction in Global Axis. |
| Unit Number Pressure Tree | Stress YY | * Stress in YY-direction in Global Axis. |
| Unit Number Pressure Tree | Stress ZZ | * Stress in ZZ-direction in Global Axis. |
| Unit Number Pressure Tree | Stress XY | * Stress in XY-direction in Global Axis. |
| Unit Number Pressure Tree | Stress YZ | * Stress in YZ-direction in Global Axis. |
| Unit Number Pressure Tree | Stress ZX | * Stress in ZX-direction in Global Axis. |
* DataTree organised as { CaseID ; Permutation ; ElementID } fx. {1;2;3} is Case 1, Permutation 2, Element 3, where each branch contains a list of results in the following order: Vertex(1), Vertex(2), ..., Vertex(i), Centre +ve stresses: tensile (ie. +ve direct strain)
