Help, trying to generate mesh from gambit to export to fluent
 

Hey everyone, currently i am doing a final year project on energy simulation in an office room building. Due to software issues, my university only provides gambit and fluent for CFD simulation. I have so far modeled a 3D model of my room, size 10.14x7.6x2.9. Inclduing radiant cooling panel, lights, inlet/outlet, tables and monitors, however i am having problem trying to mesh it, currently trying to mesh it at 0.1 intervals. Any variation of the mesh for the volume meshing that i have tried is unable to work. So far edge meshing is at 0.1, face meshing is quad/tri map at 0.1.
Any help would be greatly appreciated, and i am on a tight deadline.
Thank you

check the volume is closed and do only tri for face and tetra for volume
