[deal.II] Re: Datapostprocessor first derivative based on what?

Jaekwang, DataOut creates data at each corner of each cell. However, DataOutFilter[1] allows to reduce the number of data to just one value for each vertex. Answering your question: DataPostprocessor doesn't choose a value but the output includes all of them. Best, Daniel [1] https://www.deal

Re: [deal.II] help with set_material_id and set_boundary_id

Hi You can set boundary id to unsigned int in type.h and dof_tools.inst.in. I personally recommend this setup if you read in a gmsh file. Then you can treat it as unsigned int. Otherwise, you need to cast boundary id safely to get correct value. Another reason to configure deal.ii this way is

[deal.II] Re: Possibility to output stuffs on the integration points?

Hi I dont know if I understand your request correctly, but I guess you want to output vertices(Nodes) and its associated solution/result right? If this is correct, then following might help you: make sure you are using shared or general triangulation without refinement by deal.ii if you are us

[deal.II] Datapostprocessor first derivative based on what?

Hi, all I have asked specific implementation of Datapostprocessor Class a week ago. Adding to that.. I suddenly become curious how this class take 'the first derivative' form the solution vector. For example, if I solve flow problem with Taylor hood element as step-22 tutorial program, and t

Dear Giovanni, This bug was confirmed and fixed , so hopefully if you try this now with the development version you should no longer have any issues. Thanks again for reporting the problem! Best, Jean-Paul On Tuesday, July 25, 2017 at 10:13:51 AM UT
