[Anton Gladky <gladky.anton@xxxxxxxxx>]

Hi Vaclav, thanks for suggestion, it seems, I have fixed it.

When I ran some tests with old variant and a new one (with null-vector
checks), I got a little bit different results with regular-hexa. Does it
mean, that in some cases geometry was wrongly calculated previously?
