Taubin Smoothing

sr2s10	sr2s10

Smooth with various number of iterations:

automesh mesh \
--remove 0 \
--xscale 0.5 --yscale 0.5 --zscale 0.5 \
--xtranslate -12 --ytranslate -12 --ztranslate -12 \
--input spheres_resolution_2.npy \
--output sr2s10.exo \
smooth \
--hierarchical \
--iterations 10

automesh mesh \
--remove 0 \
--xscale 0.5 --yscale 0.5 --zscale 0.5 \
--xtranslate -12 --ytranslate -12 --ztranslate -12 \
--input spheres_resolution_2.npy \
--output sr2s50.exo \
smooth \
--hierarchical \
--iterations 50

Quality Metrics

Assess element quality to avoid oversmoothing:

automesh mesh \
--remove 0 \
--xscale 0.5 --yscale 0.5 --zscale 0.5 \
--xtranslate -12 --ytranslate -12 --ztranslate -12 \
--input spheres_resolution_2.npy \
--output sr2s10.inp \
smooth \
--hierarchical \
--iterations 10

automesh metrics \
--input sr2s10.inp \
--output sr2s10.csv \

With figio and the hist_sr2sx.yml recipe, we obtain the following element quality metrics:
