Hello Everyone,

I would like to linearly interpolate the file attached below on a rectangular zone having the same extrema as the x/T and z/T of the file.

To create the rectangular zone I do:

Data --> Create Zone --> Rectangular
I=350, J=350
XMin=-2, XMax=4.75
YMin=-1.5,YMax=1.5

To attach the file to the zone I do:

Data --> Interpolate --> Linear
but i cannot choose my dataset as a Source Zone. How can I solve this problem?

The Problem arises only with Linear Interpolation. Indeed, I can do both Inverse-Distance interpolation and Kriging.

Any explanation is appreciated,

Thanks in advance,

Z

The Tecplot 360 user manual http://download.tecplot.com/360/current/360_users_manual.pdf on page 282 states:

Use the Linear Interpolation dialog to interpolate data from one or more ordered or finite element zones onto a destination zone. Irregular I-ordered data cannot be used for the source zones in linear interpolation.

I believe the data set you supply has 1-D dimensionality (it is only I ordered), so Tecplot does not know how to linear interpolate from 1-D to 2-D (so it does not offer you the option).
