hello
I have a problem with solver when I input my airfoil and do batch analysis on it then I send as .XFLR5 file into Flow5 model and build my model and run T1 the problem is shown ((can’t be interpolated)) are this problem related to use canard in my model ? how i can solve this problem ? and if there is any expert from Flow5 company i can meet you to show you the problem and do all thing to solve it.

It says that locally the lift coefficient is 1.7 or more. This value is greater than what the airfoil can achieve, hence the drag coefficient cannot be interpolated.
It is explained in detail in this document:
http://www.xflr5.tech/docs/Point_Out_Of_Flight_Envelope.pdf
The bottom line is that these operating points are too distant from the conditions for which solvers like xflr5 and flow5 are valid. The inviscid assumption implicit in the potential flow solver is not good enough in this case.
Hello,
Please post the content of the log file here. It should point to where the problem lies.
