Patran Graph utility for plotting through the thickness stresses along a curve.
- Create a curve through the area of interest:
- Geometry Tab -> Create -> Curve -> Points
- It is recommended to use existing nodes rather than use arbitrary points
- Plot the through-thickness stress:
- Results Tab -> Create -> Graph
- Select Subcase of interest and Stress Tensor Quantity
- From the ‘X:’ dropdown select Path Length
- Click on the Target Entities button
- From the ‘ Display Control’ dropdown select Path
- Select Curves of interest
- When plotting multiple curves Patran will visually connect the plotted lines. The exported data should be outputted correctly.
- Press Apply
- There are two options to export:
- Utilities -> Results -> Write XY Curves to File
- Drawbacks:
- File format cannot be changed from .xyd
- Each curve is exported as a separate curve
- Tools -> Results -> Explore (recommended)
- From the ‘Object’ dropdown select XYPlot
- Click on the Export button
- Select all curves to be exported
- Change .xy file extension to .csv
- Drawbacks:
- Utilities -> Results -> Write XY Curves to File
- General Tips:
- Changing the Global Tolerance (Preferences -> Global) will affect how points are taken along the desired curve. It is recommended to keep the global tolerance at the default setting.
- Depending on mesh density, global tolerance, and number of points requested it is possible to receive a message: “… interpolants lie just outside the field. Extrapolation attempted. These values should be checked for accuracy. It is best if all interpolants are within the field mesh.”
