Gradient Meshing Near Crack in Neper

[vikramroybarc]

Dear Sir,

I am currently working with the following tessellation file in Neper:

I would like to know if it is possible to perform gradient meshing in Neper — specifically, to create finer elements near the crack region and coarser elements elsewhere.

I attempted the following command:

neper -M n10-id1_cut.tess -elttype 'hex'  -rcl "abs(y-50)<5 ? 0.2 : 2"

However, this does not seem to produce the desired effect. Could you kindly advise if gradient meshing near specific regions (e.g., the crack) is supported, and if so, whether this command needs to be modified?

Thank you for your time and guidance.

Best regards,

[rquey]

It is possible using [-cl{ver,edge,face} or -rcl{ver,edge,face}], which allows to specify individual values for the individual entities.

 neper -T -n 10 -dim 2
 neper -M n10-id1.tess -clver "(id==1)?0.001:0.2"  -pl 1.1
 neper -V n10-id1.msh -dataelt2dedgerad 0.001 -print d
