Hi everyone

I have done an axisymmetric flow in Fluent with the geometry at the order of magnitude of 10e-9 m. Now I want to rotate the flow field to get 3-D results (cylindrical coordinate to cartesian coordinate)and then interpolate it as I do not need that many grids.

I have tried to use CFD-post, it can not show and export the results correctly due to the nano-geometry I am using, although it can rotate the flow field along axis.

I also tried the "Data-Alter-axial roation" in tecplot 360 2017 version, the problem is that tecplot does not show the 3D view after rotation which disables me to define the region where I want to do the interpolation.

I finally export the data from fluent to matlab and do the rotation and the interpolation, but the interpolated results near the boundary are not very accurate due to the built-in interpolation method in matlab.

Any suggestions to do the rotation and interpolation.

Thanks a lot!
