In a simple hexa mesh flow around a 2d square cylinder i am getting determinet -1 in some regions?

08 April 2019 1 10K Report

i am working on a FSI problem with one way coupling. I am trying to mesh my fluid domain with ICEM . In pre quality check i am geeting det 2*2*2 -1 which should be greater than 0,3. i am attaching my geometry and bad cells . i am very new in this field . any help will be big advantages.

My procedure this now.

-Create geom.

-supress solid part

-import geo in ICEM

-Create blocks

-edge sizing

-mesh check
