[Gmsh] Reduce number of digits in key-format file

[Xingsheng Sun]

Hello All,

I am using Gmsh to generate the mesh file for Ls-dyna. The problem is that
in the key-format file generated by Gmsh, the coordinates of nodes have too
many digits. For instance, in the node information:

*NODE
22, 0, 0.012499999999976, -0.001
23, 0, 0.02499999999995, -0.001
24, 0, 0.037499999999926, -0.001
25, 0, 0.049999999999907, -0.001

the y-coordinates of nodes 22-25 have 15 digits that cannot be read by
Ls-dyna.

So could any people shed light on how to reduce the number of digits in
Gmsh? I am using command lines, not GUI. Thank you so much in advance.

Best regards,
Xingsheng
