### CYL2, $l$, ${R}_{0}$, ${h}_{0}$, $\epsilon$, $i$

Creates a half-cylinder. Several CYL2 commands are not allowed. A combination with BLOCK and CYL4 commands is not allowed. Tube imperfection, described by parameter $\epsilon$, is defined analogously as in case of the CYL4 command.

Parameter Description
$l$ cylinder length
${R}_{0}$ cylinder inner radius
${h}_{0}$ cylinder thickness
$\epsilon$ imperfection
$i$ order of imperfection (default value is 2)
