Dear experts, I am running postw90.x to calculate AHC but the run gets stuck in reading Distance to Nearest-Neighbour Shells. I have tried running it with parallel as well as serial executable. I also tried running the calculation with versions 2.1.0 and 3.1.0. In all the cases the run gets stuck. I have attached the input and output files here ( https://drive.google.com/drive/folders/19yv27cVHbiFtFGPGP1GcSZocQXmCVZfr?usp=sharing ). Any help or suggestion would be highly appreciated. Thank you.
