[Dune] info DGF file

[claudia.bortolussi at uzh.ch]

Dear All,

I'm trying to understand better how the dgf file is structured; I am focusing on the "blood flow" example and on the "root-soil" one because I'm going to work on similar grid network.
In particular I would like to understand what does "parameters" stand for under the SIMPLEX block. For example, which is the difference between this two dgf file?

(brain.dgf from thr bloodflow example)
SIMPLEX
parameters 2
0 1 4.5e-06 0.0075
1 2 3.5e-06 0.0015
1 3 3.5e-06 0.005
3 4 3.5e-06 0.003

(lupine.dgf from the root-soil)
SIMPLEX
parameters 4
0 1 1 1 1.789900e-05 9.298100e-03 # simplex 0
1 2 1 1 9.789900e-06 7.298100e-03 # simplex 1
3 4 1 1 8.642000e-06 5.687800e-03 # simplex 3
4 5 1 1 7.492900e-06 4.278200e-03 # simplex 4


Thank you.
Best regards,

Claudia Bortolussi
