The geometry can be observed on the following website: http://www.vascularmodel.org/miccai2012/.nAccording to literature, the flow can be stabilized by creating a hybrid mesh. This means making most of the inlet and the descending aorta a mesh consisting of hexahedral elements with a boundary layer, while the arch (including the branches) has tetrahedral elements, also with boundary layer.nI can make a mesh consisting of solely tetrahedral elements, with a boundary layer, in ANSYS ICEM. However, I am struggling a lot with the creation of a hybrid mesh when my starting point is an imported .stl file. I have followed several tutorials concerning blocking and hybrid meshing, but none of them seem to be useful for my geometry.nTherefore, I was wondering if someone here has experience/knowledge on how to create such a hybrid mesh? My final mesh should look like shown here: https://www.semanticscholar.org/paper/CFD-analysis-of-blood-flow-within-aorta-of-patient-Rojczyk-Ostrowski/75baa27459928a3fd3333f7235fe4158219dda3a/figure/0nThanks a lot!nnKind regards,nnMichellen

Save .uns file and then create tet mesh and save another .uns file. Then read those 2 uns files in one session and then merge them. nPlease see help manual for more details about these commands. nnRegards,nKeyurnGuidelines for Posting on Ansys Learning ForumnHow to access ANSYS help links
