Post-processing
The options available under Post-Processing are optional and they can also be set later in the Result Viewer of the result file (*.gdr) after the computations.
The options in the ElastoDict-Effective Stiffness settings are shown here.
How they look in the Result Viewer is shown below. Post-Processing in Original Coordinate System is always available and selected by default. All other post-processing options are only available if all load directions (XX, YY, ZZ, YZ, XZ, and XY) have been previously checked under the Load Case tab.
Stress Unit
When post-processing the plots in the Result Viewer, the Stress Unit for the results can be selected. This choice has an effect on the values under the Report subtab and on the Plots subtab. The stress unit in the Results – Map subtab is always GPa.

Post-Processing in Original Coordinate System
Check Post-Processing in Original Coordinate System to compute the engineering parameters and elasticity-tensor approximations in the original coordinate system (X, Y, Z).
|
Post-Processing in Principal Material Axes (PMA)
Check Post-Processing in Principal Material Axes (PMA) to find the PMA of the material and compute the engineering parameters and elasticity-tensor approximations in the PMA system. This is only possible if all six load cases (under Load Case tab) are calculated.
|
Post-Processing in Principal Material Axes (PMA) in the XY-Plane (fixed Z-Axis)
Check Post-Processing in Principal Material Axes (PMA) in the XY-plane to find the PMA of the material in the XY-plane and to compute the engineering parameters and elasticity-tensor approximations in this PMA system. This is only possible if all six load cases (under Load Case tab) are calculated.

Compute Direction-Dependent Stiffness
Check Compute Direction-Dependent Stiffness to calculate the material stiffness in the XY, XZ, and YZ plane, in the original coordinate system. Additionally, the material stiffness can be analyzed for arbitrary angles. With the Angle Resolution (°) setting the angle steps for this calculation is defined.
The result file obtained after computations includes a table showing the calculated Young’s Modulus E in the three planes according to the entered angle resolution. Additionally, a plot for the direction dependent stiffness can be found in the results file under the Plots tab.

Export Abaqus UMAT for Anisotropic Material
When Export Abaqus UMAT for Anisotropic Material is checked, an UMAT with the computed anisotropic material properties is exported and can be found in the result folder. This UMAT can directly be used in Abaqus, or it can also be used as material in GeoDict.

Compute Norris Approximation
Check Compute Norris Approximation to compute the cubic elasticity tensor approximation following Norris, 2006. See also the section about the Effective Elastic Properties for a more details discussion on the results. This is only possible if all six load cases (under Load Case tab) are calculated.
