I need help modeling this in ANSYS Workbench.

An open thick cylinder shown below has an inner radius, a $=1$ m$,$ outer radius, b $=1\mathrm{.}5$ m$,$ length L $=6$ m$,$ and has a pressure load p $=10$ MPa applied on the inner surface. The cylinder is free to deform along the length. Compute the radial and tangential stresses in the cylinder in ANSYS Workbench by using symmetry to model only half the length of the cylinder and use a $2-$D axisymmetric analysis to model the $2$D cross$-$section of the cylinder that represents the $3$D solid of revolution. Assume Young$$s modulus, E $=200$ GPa and Poisson$$s ratio, $=0\mathrm{.}3.$
