This is a plugin source code for the NEK5000 data format, for use with version 5.1[01] of ParaView

How to compile:

Depending on the optional package you have built into your source (e.g. OSPRay, OIDN, VisRTX), you will need some extra env flags to help cmake. In my case, I explicitly set ospray_DIR, OpenImageDenoise_DIR, and VisRTX_DIR before running cmake)

mkdir build; cd build; cmake ../; make

N.B. (February 09, 2023). Thanks to the integration work of Dan Lipsa and Scott Wittenburg at Kitware, the code has now been integrated into VTK and ParaView. Using a nightly download (more recent than v5.11), yuo will have the native reader in ParaView.
