Reference Points Losing Their Location

Hi all,

Anyone else experiencing a strange behaviour of Reference Points moving arbitrarily away from the associated referenced surfaces ?

This seems to happen after the solver has completed it’s run. In version 2.4.3.

The strange part is that the surface is still referenced in the selection window. However, the X,Y,Z corodinates have changed

I am sorry for my late reply but could you share the file? What units are you using an how large is your model (the scale bar is not visible). Are the results in the same units?

Thank you for the model. I think it also shows the problem where the file gets corrupted when opened in a newer version. I hope this will enable me to find both bugs.

Looking at the model, I think the unit system got mixed up. The point positions are scaled by a factor of 1000. But I cannot reproduce the reference points flying away. Did it happen only once, or multiple times? Do you remember what you did exactly? I fixed the RPs’ positions, ran the model again (deactivated contacts), and when I open the results, the RPs keep their positions.

But I discovered that for larger models, the selection cache was not working efficiently enough, so I fixed it, and now opening RP properties is much faster.

It happened once, but I cant recall exactly when. I think it was after i ran the analysis.

I will keep an eye on it and see if it happens again.

Thank you @Matej

Please do. And if happens again try to reproduce it.
