Problem description

When accessing the table data for any structural element (plate, geogrid, embedded beam row, Fixed end anchor, none-to-node anchor) in a Safety phase in PLAXIS 2D 2016.00, all values in the table show a N/A value. This is due to an issue in the Output program’s table rendering.

Figure 1. Force results show N/A in a safety analysis

This also affects the getresults command for Output’s command line and the remote scripting (Python), in which the getresults gives this message when retrieving structural elements data for a Safety phase (note: it works for other calculation types):

The command did not deliver any results

The structural displacements and forces are still calculated correctly during the Safety’s deformation calculation, but the results are just not accessible in the Output program.

Solution

This issue has been resolved in PLAXIS 2D 2016.01!

When still using PLAXIS 2D 2016.00, there is one workaround available, that uses the curves feature in Output with post-calculation selected nodes.

Node to node anchor

These steps should be followed to get the force for a node-to-node anchor:

1. Open the Output results of the safety phase
2. Note the step number of this phase, since we will need it later to read the results from a curve
3. Locate the two endpoint coordinates of the desired node to node anchor
4. Now open the curves manager
5. In the third tab sheet (Select points) fill in the coordinates of one of the two end points
6. One of the items in the lower pane, should read Node-to-node anchor. Select this one.
7. If this node is not found, use the other end point’s coordinates
8. Now make a graph of step vs. Axial force for this node
9. You can open the table and find the appropriate step to read the exact anchor’s axial force

For other structural elements, you can use the same approach by selecting a node after calculation.
