Geometry-based mesh induces 'excessive displacements' warning. Bug?

Hi

 

I'm trying to run a static analysis on a simple assembly, but I keep getting the 'Excessive displacements were calculated in this model' error when curvature-based mesh is used:

 

I cannot go ahead using Large Displacement as the screw is distributed and not rigid. If it went ahead without using Large Displacement, the resulting displacements look very wrong.

 

However, the analysis runs fine without the warning if standard mesh was used. Does anyone know why geometry-based mesh results in such a strange error? Is it a bug? I've attached the model (SW2020).

 

Thanks
