Re: [deal.II] Re: Meshworker in dim=2, spacedim = 3

[Daniel Arndt]

Andrea,

This should be fixed upstream now. Have a look at PR #4265 [1].

Best, 
Daniel

I might have to convince Luca to try it.


Alternatively, can you create a small program that shows the compiler 
error? It doesn't have to do anything useful, just set up the necessary 
data structures and then call the function that gives the error.


Someone else could then try with your little program. If you open a bug 
report at https://github.com/dealii/dealii/issues/new I bet someone will 
take a look at it within just a couple of days (but may not be able to 
fix all downstream problems, if there is more to do than just add the 
one template argument).


Best

Re: [deal.II] Re: Meshworker

[sudarshan kumar]

Yes the FEValues defined for each dell dinfo1.cell  and dinfo2.cell
provides  all the interior information of the cells( however  I did not
succeed in the accuracy test  so far, but it works ).

In fact,  apart from the interface  values  I need  solution  values  at
the interior  of   each cell,  usually  for  time dependent problem this is
not really needed ( only the limit value at the face  is required from each
side of the face). In my case the method is a bit different, here to
compute the interface flux it needs to know few values of the solution in
the interior as well.( I am not sure if it is  an efficient way to compute
it in the call  integrate_face_term in the meshworker set up).

Thanks  a lot.

But don't the FEValues objects you get for the face provide these values? I 
mean, they evaluate the solution and shape functions on either side of the 
face. In other words, while the quadrature points for these two objects have 
the same physical locations, they evaluate the elements as the limits of 
points coming from each of the cells, and consequently the values are 
different even though the points are the same.


Or do you need to evaluate the solution at points inside the cells that are 
not in fact on the interface?
