Hi, I'm currently attempting to just simply run RANS solvet for a RAE2822 airfoil, meshed in gmesh. However I keep getting an error in SU2 that I don't recognize or am able to find a solution to.

Strangely SU2 seems to run fine until it comes to writing the solution file so depending on what iteration that is set to it will run up till that many iterations then exit with one of two errors, which it switches between one after the other each time I try and run it, either:

Or:

I'm fairly confused and need to fix this ASAP. If anyone has any ideas that would be of great help!

Could it be to do with the splines in my gmsh file?

I'm not concerned about the correct mesh size or boundary layers etc at the moment, just getting it to run as a coarse mesh on SU2 is the priority.

Ive attached the .su2, .cfg, and second error (as it was too many characters) file. Any help or suggestions would be greatly appreciated.
