Hi Asim, I think the interpolation routines used in this module are not implemented for homogeneous expansions yet. If the locations in z where you need the data coincide with the homogeneous planes, one possible alternative is to first use the homplane module to extract a single plane, and then use interppoints to probe the point at that specific plane. This involves more work, since you have to repeat the process for each plane, but it should work. Cheers, Douglas ________________________________ From: nektar-users-bounces@imperial.ac.uk <nektar-users-bounces@imperial.ac.uk> on behalf of Asim Onder <asim.onder@nus.edu.sg> Sent: 19 October 2016 08:06:49 To: nektar-users Subject: [Nektar-users] about interppoints Dear Nektar users/developers, I’m doing some simulations in 3D1H, and trying to extract data along a line in homogenous direction using interppoints module. However, the output contains constant data, shows no variation along the points. I was wondering if interppoints contains a bug or I’m just doing something wrong. Here is the command I used, and I also attached the config file and the output. FieldConvert -v -m interppoints:fromxml=config.xml:fromfld=fields/field_48.chk:line=1080,0.0884,0.009,0,0.0884,0.009,0.406 pointData/kMax_48.dat Thank you very much in advance for any feedback.
