Hi Guillermo, Did you ever get to the bottom of this. There is a function in FieldConvert to increase the number of Fourier planes a file is output to. It is the --output-points-hom-z option? So --output-points-hom-z 16 Should output to 16 points. Cheers, Spencer.

Dear all,
I have performed a quasi 3D simulation, being the z-axis the homogeneous direction, with an homogeneous length equal to 0.1 (LZ=0.1) and up to 3 Fourier modes (HomModesZ = 4). In that sense, my planes are located at: 0, 0.025, 0.05 and 0.075. I want to interpolate the solution to a series of points, thus I am using the interppoints module. These points are located along the z direction and between the Fourier planes, e.g., z=0.033, 0.066 etc. The output file from the FieldConvert -m interppoints command is quite strange, since each variable is constant along the z direction, and of course, it is not the actual case. I have also tested it for another set of points. In this second test I have changed the z-coordinates and fixed it to the Fourier planes. However, the result is the same as before, constant measure for each variable and with exactly the same value as for the first set of points. So, is the interppoints module implemented for the 3DH1D simulations?
I would like to mention that on the user guide, the commands shown for the usage of the interppoints module, except for the first example, they are missing the output "file2.dat".
Thank you.
Regards, Guillermo
