For the selected nodes and stress points for curves, PLAXIS will store all selected nodes and stress points by their node number and stress point number respectively in order to use these as references to gather the data for curves. These selections are stored in two categories:
When regenerating the mesh with a changed configuration (e.g. different coarseness, changes in geometry), the node numbers and stress point numbers at a given location will change, meaning that the stored node numbers and stress points are only valid for one mesh configuration.
The PLAXIS 2D AE program will reset the pre-calculation selected nodes to avoid incorrect node/stress point references, but unfortunately, it does not reset the post-calculation selected nodes and stress points in PLAXIS 2D AE.00 and PLAXIS 2D AE.01. This can lead to two problems:
This issue is now solved in PLAXIS 2D AE.02: when regenerating the mesh, the pre-calculation stress point and node list and the post-calculation node and stress point list will be cleared.
In PLAXIS 2D AE.00 and PLAXIS 2D AE.01, the above mentioned problems could be solved:
