Number of double nodes is reported inconsistently

Posted by Massimiliano Leoni at March 21. 2019

For the mesh I am working with, asking for the number of double nodes from the "Quality info" panel and from Controls->Node controls->Double nodes gives different results. See attached screenshot.

In this case I know that the mesh has double nodes because when I load it in my solver it crashes. A related bug is that the same mesh, scaled by 1000, has no double nodes.

Additionally, if I try Modifications->Transformation->Merge nodes, it will tell me that there are no double nodes and will not fix my mesh.

Other update: the double nodes were in one of the submeshes. Using "Merge nodes" on the submesh directly successfully removed the double nodes. However, there is still something wrong with the mesh, since a certain code I am running on it crashes. If I run it on the mesh obtained by scaling this mesh by a factor of 10, then my code works fine.
