How to query the minimum mesh size in a model

General Questions
1

I used prepomax to divide the mesh and now want to query the smallest mesh size among them.

2

Check Model → Element → Element Quality → minEdge.

There is no Element Quality.

Which PPM version are you using ?

5

Element quality tool was added in v2.2.0.

6

OK, I am using v2.1.0.

I can not open it to download v2.2.0.

This link can download.

There is such a paragraph in the output file：
Scaling factor of time increment: 6761.5076701904964
How to calculate this value?

So you are running a dynamic explicit analysis and it’s about mass scaling. The following description is provided in the CalculiX User’s Manual:

In CalculiX, selective mass scaling is triggered by specifying the minimum time increment ∆t_target which the user is willing to tolerate underneath the *DYNAMIC keyword (third parameter). If for any volumetric element the increment size ∆t_stable calculated by CalculiX (based on the wave speed) is less than the minimum, the mass of this element is automatically selectively scaled. In that case a message is printed and the elements for which the mass was redistributed are stored in file “jobname WarnElementMassScaled.nam”.
