   **group_axisymmetric**  *index*  *switch*

If switch is set to **-yes**, the calculation becomes axi-symmetrical for the group *index*. Each specied :math:`x` coordinate becomes a radius and :math:`y` becomes the length (=vertical) direction. The :math:`z`-direction is the axi-symmetric direction. Specify only non-negative :math:`x` coordinates, i.e. define the computational domain in the right half-plane. This option is only available for groups with isoparametric 1D elements (bar2, ...), or isoparametric 2D elements (tria3, quad4, ...), or for 2D interface elements (quad4 interface, ...).
