When checking the calculation, the following message appears: "Error No. 16 when generating the FE mesh. Two or more nodes have the same coordinates."


In this case, you can try to adjust the FE mesh finer.

However, it is usually better to regenerate the model and to round off the node coordinates to 6 decimal places, for example. You can access this feature using the menu "Tools → Regenerate Model." In this way, the inaccuracies caused by the smallest differences in a coordinate are corrected (see Figure 01).

The model check can also find double nodes (menu "Tools → Model Check → Identical Nodes"). In the following dialog box, you can specify what is to happen with these nodes (see Figure 02).
