Thanks @Mick3Lozzo. Few points:

  • Do you have a source for the value of the parameter PTC_MASS_DENSITY ?

It's in the datasheet @fiorisi.

For NdFeB magnets, the physical properties are different than for 100% Neodymium.

See this link.

7.5 Kg for cube meter? Seems low, in the file you actually set it to 7.5 g / cm^3

In the other table, I saw 7.5 g/cc. I suppose "cc" is cm^3 @fiorisi.

@fiorisi for all the materials We have Initial Bend Y-Factor = 0.5

We can consider it as a sort of default value?

Done @fiorisi
