3d second order mesh have zero volumes

3d second order mesh have zero volumes was created by DU
Hello, everyone
I use netgen to generate 3d second order mesh (C3D10) by .geo. And I export mesh to Abaqus format for calculations. But it always has elements with zero volume.
I have tried to limit different minimum size of mesh but it doesn't work.
But if I don't 'refinement-second order' which means I use first order mesh, there's no problem.
What can I do to avoid zero volume mesh and has second-order mesh?
Thank you all.
