202 PetscConvEstGetConvRate - Returns an estimate of the convergence rate for the discretization
203
204 Not collective
205
206 Input Parameter:
207. ce - The PetscConvEst object
208
209 Output Parameter:
210. alpha - The convergence rate for each field
211
212 Note: The convergence rate alpha is defined by
213$ || u_h - u_exact || < C h^alpha
214where u_h is the discrete solution, and h is a measure of the discretization size.
215
216We solve a series of problems on refined meshes, calculate an error based upon the exact solution in the DS,
217and then fit the result to our model above using linear regression.
