Re: [deal.II] step-35 in modified
Dear Jack,
as the compiler error says the variables are not defined in the respective
scope. You define vL2_error, pL2_error, vH1_error, pH1_error inside the for
loop from line 1803 to 1861. Outside this loop, the variables are not
defined anymore. The same applies to the variables vLinfty_error and
pLinfty_error, lines 1897 to 1923.
Best wishes,
Sebastian

Re: [deal.II] step-35 in modified
I want to generate convergence table for the modified step-35 for a couple
of velocity and pressure error norms.
The problem seems to emanate from my definition of the errors in

Dear all, a colleague and I have also worked with step-35 and we programmed a parallelized version whose layout is similar to that of step-32. Currently, the code is not suitable to be directly used as a tutorial, but, if you are interested, we could refactor it and send it through github as a step-35b.

[deal.II] step-35 in modified
Hie. I am working on flow problems with a model based on the NSE. The project involves using adaptive finite elementts, and first steps are to: 1) have a mesh adapting strategy 2) compute errors 3) obtain convergence rates I am basing these on the dealii step-35 and have attached my attempt to implement these 3 , and would you to point in the right direction. I have attached the amended code here, and would like suggestions on how to make it work. The error is that at line 1050 /"a function is expected at ,..." / How do you implement this in an amendment to step-35? mathematical sciences 15015 Ganges road p.o box be277 belvedere harare zimbabwe business: +263.24.274.1423-36 fax : +263.24.274.1408 mobile zw1: +263.77.283.8167 mobile zw2: +263.77.412.0815 mobile ind: +91.844.867.9322 home : +263.68.215.3910 -- The information in this message is confidential and legally privileged.
