I get FATAL

.out messages mention CQPSTN element node numbering, renumbering, & likely related problem with CONTACT there.

.out suggests to re-import the model, export etc will fix this … but it is not resolved.

.out describes element normals need to be positive. … but it is not resolved.

My model is on the XZ plane.

QUESTION: How can I fix my model?

.out message pasted here:

*** WARNING # 2502
Element 427 had incorrect node numbering sequence and needs renumbering.

....more messages about the elements with incorrect node sequence suppressed.
Note : Please import the model into HyperMesh and export it. This will fix
the problem related to the incorrect node numbering.

*** WARNING # 2501
13560 elements had incorrect node numbering sequence and had their nodes
renumbered. This will affect the orientation of respective element
coordinate systems. If there is any CONTACT/TIE defined on these elements,
an error will be triggered.

*** WARNING # 6571
For CQAXI, CTAXI, CQPSTN, CTPSTN, CQPSTS, CTPSTS and CTRIAX6 elements, the
out-of-plane normal direction defined by the corner node sequence with the
right-hand rule should point to the positive z direction if the element is
in the x-y plane, and, the positive y direction if it is in the x-z plane.
