rmcell command is buggy

[anujyadav0693]

HI,
I am using this code to remove cell to create voids in microstructure.
neper -T -n from_morpho -morpho "diameq:lognormal(0.1,0.01)+0.5*lognormal(0.01,0.001),1-sphericity:lognormal(0.145,0.03)" -transform rmcell(diameq<=0.01) -dim 2 -domain square(1,2)
is not working
is rmcell is buggy command
thank you

Yes, rmcell is buggy. As a workaround, you can use -meshpoly (or -meshface, in 2D), with the complementary logical expression, to mesh only the grains matching that expression. For example:

neper -T -n from_morpho -morpho "diameq:lognormal(0.1,0.02)+0.5*lognormal(0.02,0.004),1-sphericity:lognormal(0.1,0.03)" -dim 2 -reg 1 -o d
neper -M d.tess -meshface "diameq>0.05"
neper -V d.msh -dataelt1drad 0.003 -dataelt2dedgerad 0.001 -showelt1d all -print img

sir,
when i am trying to use meshing code neper -M d.tess -meshface "diameq>0.05". i got this problem meshing is not done.

neper -M d.tess -meshface "diameq>0.05"

Did you run ctest to test the program when you installed? The latest version is 4.5.1-1; you many also want to upgrade...
