Hi Nathan,
I might be mistaken, but I think that the new advanced feature providing up to three numerical wave gauges has not been included in the master branch of WEC-Sim. It follows that the latest version of WECCCOMP cannot run (as the new property ‘waves.wavegauge<i>loc’ is unknown). The new feature is included in the ‘gh-pages’ branch, though.
Cheers,
