Wind Tunnel - Z values must be 2 not 8?

Hi all,

So I got a error at Create Case from Tunnel
“Z values must be 2 not 8”
Any idea what could this possibly be?

Any helps is going to be appreciated!

Hi @tutu7931 You should post more details about the wind tunnel setting.

Thanks, I think I got that problem solved.
At some point maybe I have single flat planar surface input as geometry so it went wrong…
