Sometimes when trying to add a curve of a pre-calculation selected node (pre-calc) from another project by choosing the option Add curve ► From another project (pre-calc)…, the PLAXIS 2D2011.02 program responds with an error message.
The Output program tries to read in the numbers of the selected nodes to determine the available data. When in the second project the selected node number exceeds the number of nodes available in the already opened project, this error message is triggered.
Two workarounds are available
This issue is solved since PLAXIS 2D2012.01
