So far it would be enough if I have the Gauss point values only at the points
rather than having complete field. I like to access these point values of
stress and strain tensors in .vtk file or .pvtu file through ParaView (same as
I am accessing the results currently).
I would be grateful if you or any other user has experience in this regard or
know about relevant deal.ii tutorial dealing with same feature.
deal.II has functionality to output data on individual points if that data is
associated with particles. I don't know how much work you want to invest in
getting this to work for you, but here are two options:
* Easy: Create a ParticleHandler object, loop over all of your quadrature
points, and for each quadrature point you create a particle. You can then
associate "properties" with each particle, and use Particles::DataOut to
output these properties in the same way as you would use DataOut for field
data. You can probably figure out how this works by looking at the draft
step-19 tutorial program:
https://github.com/dealii/dealii/pull/10301
* More work, but more elegant: You could write a class, let's say
QuadraturePointData::DataOut or something similar, to which you could describe
the information of location + values without the detour of particles. I'm sure
we'd be happy to walk you through the process of doing so if you wanted to go
for that, and it would be a very nice addition to deal.II if you wanted to get
it merged.
Best
