Notes

  • Using a scaled unit cube ([0,1]3) and Polar-1 metric from UGAWG
  • No boundary adaptation,due to the increasing prepossessing time and the difficulty to recover the boundary.
  • mrecm2 needs to be disabled due to problems with inpshere falling in infinite loop
  • mrec4 needs to be on or highly anisotropic elements will not be refined ( this is due to the double flag omission of CDT3D)
  • 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
  • Using 24+24 (HyperThreading) threads
  • parameters --met=1 --meval=2 --mrecm2=1 --mrec4=1 --nadapt=0 --mpp=2 --qstatr=1 --outmesh=${NAME}.meshb --ndfs=0 --nthreads=24 --nbuckets=640 --nthreadsaf=24 --nbucketsaf=640 --blockmul=500000 --nqual=0 --nminpts=30 --ordt=1 --pardeact=1 --mdse=0
  • raw data is under crtc-gpu.cs.odu.edu:/research/ctsolakis/QCIRCLE
  • corresponds to commit bfb2e8589342bd2724701fa43f31a9ebb02bba6c , and tag WIKI_UGAWG
