Howto create higher order elements?

I am new to Trelis and I was able to create tet meshes successfully. But I can’t find an option to create higher order elements, e.g. second order tets. How can I do that with the help of the GUI or the command line.

Thank you,
Thomas

Element type are assigned to blocks. You would create a block of the volume and then assign a type to the block. An example of the commands would be

reset
bri x 10
vol 1 scheme tetmesh
mesh vol 1
block 1 vol 1
block 1 element type tetra15

Or you can use the GUI
