Hi, i am trying to establish a corelation between my aerodynamic and structure grid for combined Aerodynamic and structure analysis. Here i am getting the X,Y and Cp from aero data and trying to obtain the data on the points given by structure mesh. So, to do that i am defining look up tables from 'Sample2DCpDistribution_Sorted.xlsx' and input to tables from 'Learn.xlsx'. kindly help me to sort out this problem. I have attached all the relavent files and model.
"Values of 'BreakpointsForDimension1' in 'wing_analysis/1-D Lookup Table' must be strictly monotonically increasing. The problem occurs at element 2. Change the breakpoints data or use the fixed-point tools such as Auto Scaling or Fixed-Point Advisor to determine a different parameter dialog type."

For lookup tabel data, you need to make sure the value of the breakpoint data is strictly increasing.

Thanks for your reply sir. In my attachment file 'Sample2DCpDistribution' are in the noral form and the values of the same data sorted out in file 'Sample2DCpDistribution_Sorted' in increasing order of the breakpoint but still problem is same in computing Y values for the given input.
