Creates the equilibrium solver and solution object, then pre-allocates arrays for temperature, species mole fractions, and convergence flags. Each nested-loop iteration writes only to these arrays.

```python
solver = cea.EqSolver(prod, reactants=reac)
soln = cea.EqSolution(solver)

X, Y = np.meshgrid(T0, phi)
T_vals = np.zeros((n_phi, n_T0))
H_vals = np.zeros((n_phi, n_T0))
H2_vals = np.zeros((n_phi, n_T0))
H2O_vals = np.zeros((n_phi, n_T0))
O_vals = np.zeros((n_phi, n_T0))
O2_vals = np.zeros((n_phi, n_T0))
OH_vals = np.zeros((n_phi, n_T0))
convg_vals = np.zeros((n_phi, n_T0))
