Hi,
I use an in-house code for FE-analyses using the arc-length method. The
results are stored in hdf5 format. A xmf-file is generated from this to
open results in Paraview. For incrementally loaded FE-analyses so far I
have used the time as a child of each grid element as shown below.
My problem is to pass the load factor from the arc-length method
computation to Paraview in order to plot results over load.
If I define an extra child besides the time like <Load Value="0.0"/> for
the load factor it will not show up in Paraview (or I haven't found it).
The time variable seems essential and if I set aside the "real" time and
assign the load factor values to it (which can - for the arc-length
method - decrease) Paraview will order the steps strictly ascending with
time (aka load factor) which shows weird results.
One solution would be to assign the load factor as a scalar to each
node. But this would increase the results by the number of nodes.
I appreciate any suggestions,
Sven Heinrich
