Hello Claudia<br>
<br>
an an alternative for tetrahedral mesh input you can also use<br>
this dune-grid compliant implementation:<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.curvilinear-grid.org/">http://www.curvilinear-grid.org/</a><br>
<br>
curvilinear-grid<br>
<br>
1) uses the Gmsh (<a class="moz-txt-link-abbreviated" href="http://www.geuz.org">www.geuz.org</a>) tetrahedral mesh generator format<br>
<br>
2) can use real world geometry using CAD systems and STEP file
format export.<br>
<br>
3) offers curviliner tetrahedral elements<br>
<br>
Therefore, you will enjoy a lot more geometrical flexibilit.<br>
<br>
Greetings, Benedikt

<br>
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.<br>
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?<br>
<br>
(brain.dgf from thr bloodflow example)<br>
SIMPLEX<br>
parameters 2<br>
0 1 4.5e-06 0.0075<br>
1 2 3.5e-06 0.0015<br>
1 3 3.5e-06 0.005<br>
3 4 3.5e-06 0.003<br>
<br>
(lupine.dgf from the root-soil)<br>
SIMPLEX<br>
parameters 4<br>
0 1 1 1 1.789900e-05 9.298100e-03 # simplex 0<br>
1 2 1 1 9.789900e-06 7.298100e-03 # simplex 1<br>
3 4 1 1 8.642000e-06 5.687800e-03 # simplex 3<br>
4 5 1 1 7.492900e-06 4.278200e-03 # simplex 4<br>
<br>
<br>
Thank you.<br>
Best regards,<br>
