| |
| * Speed 22.5K test/sec and 3.9 ps/sec
| |
| * according to Mike's email mesh should be around 100k vertices
| |
| * Metric Input Data available at [https://github.com/UGAWG/parallel-adapt-results/tree/master/delta-wing/fun3d-fv-lp2 https://github.com/UGAWG/parallel-adapt-results ]
| |
| * Input surface is the coase mesh available at [https://github.com/UGAWG/solution-adapt-cases/delta-wing/initial-grid/delta01.meshb https://github.com/UGAWG/solution-adapt-cases]
| |
| * The experiments performed on a DELL workstation with Linux Red Hat Enterprise, 24 hardware cores Intel® Xeon® CPU E5-2697v2@2.70 GHz, and 757 GB RAM
| |
| * Memory is measured at the end of Mesh refinement and thus it may reach a slightly higher value before the point of measurement
| |
| * parameters <code> --brec=2 --met=1 --meval=3 --mrecm2=1 --mrec4=1 --nadapt=2 --malign=0 --mpp=2 --ndfs=0 --nthreads=$THREADS --nbuckets=20*$THREADS --nthreadsaf=20*$THREADS --nbucketsaf=20*${THREADS} --blockmul=500000 --nqual=0 --nminpts=30 --ordt=0 --pardeact=1 --mdse=0 </code>
