Default error in surface tetmeshing
Posts: n/a

I've imported a IGES geometry and created a surface mesh of a rectangular box as my flow domain. subsequently i imported an .stl file and tried tet meshing to fill up the inbetween spaces with tetrahedrals.

i've encountered this problem ERR 3103 : EDGE 19927 9141 INTERSECTS WITH EDGE

13847 638 ERROR:3103 - Two edges intersect in surface mesh

is there anything i can do to rectify this and facilitate my meshing?
