  We present results from the new Dendro-GR code. These include simulations of
binary black hole mergers for mass ratios up to q=16. Dendro-GR uses Wavelet
Adaptive Multi-Resolution (WAMR) to generate an unstructured grid adapted to
the spacetime geometry together with an octree based data structure. We
demonstrate good scaling, improved convergence properties and efficient use of
computational resources. We validate the code with comparisons to LazEv.
