  Have a look at mesh interfaces: those are the walls created to account for when the two faces don't exactly match. Given it's a radiation model and therefore the surfaces between the fluid and solid are important I'd suggest not using them and going back to the geometry too to make sure you create a conformal mesh. n

  That might explain the problem you see here https://forum.ansys.com/discussion/23943/fluent-crashes-as-is-writing-the-view-factor-filen
