Multi-element rear wing for racecar - Failed: Front advance failed
I have created a multi element rear wing for a racecar, simply made of two upside-down NACA 4415 airfoils that comes from the 'Flow Over an Airfoil' tutorial (www.symscape.com/node/561).
I want to eventually get some velocity and downforce data by following the 'Flow over a CO2 Dragster' tutorial (www.symscape.com/node/1082), except by using the wing I've created in place of the dragster model and adjusting accordingly. However I'm having a problem when I try to apply the Vector Fields->U to the wing, as I get the following message:
"Tetulator: End: 2675 tetrahedra
flow-volume [www.1289.5] Tetulator: Failed: Front advance failed: 568 faces remain"
I'm assuming this means there's something wrong with the meshing. I have attempted the 'Mesh Diagnostics' guide (www.symscape.com/node/995#comment-758) over the course of the past 3 hours but I have to admit I don't understand it very well as I'm new to CFD so I haven't gotten anywhere with regards to fixing the mesh or even finding out what the problem is.
I've tried and tried so posting here really is a last resort, could someone please give me some detailed instructions on what the problem is and how to correct it? It would be much appreciated! I can upload the file or something if that would help. Thanks again!
