Keyword: zzerrorestimator
Performs a Zienkiewicz-Zhu type error estimator.
Example:
numproc zzerrorestimator ee1 -bilinearform=a -solution=u -error=err
Averages the fluxes, and computes difference between averaged flux and original flux. Difference is added to element by element gridfunction error. Averaging is done sub-domain by sub-domain to avoid too strong refinement along material interfaces.
-bilinearform=<name> | first integrator of bilinear-form defines flux |
-solution=<name> | gridfunction containing solution |
-error=<name> | element-by-element, order 0 gridfunction containing element contributions of error |
