<DIV><FONT face=Arial size=2>Hello!<BR>First of all, I would like to thank you
for getDP, which seems to be a really nice tool, and especially for providing it
as free software. This is simply great! <BR>A colleague of mine and me are
working on a project wherein we want to simulate a multiphysics problem
involving numerical electromagnetism and CFD. As far as I have concluded from
the mailing list, getDP has no Navier-Stokes solver yet, and therefore we want
to couple getDP with an external CFD code (FLUENT, in our case, which sadly
seems not to have a electromagnetic solver apart from the unaffordable
ANSYS-MPCCI combination).<BR>As we have a transient problem, this would mean to
first calculate a time step with the CFD code, and then pass some relevant data
to getDP, which after doing its time step returns some data for the next CFD
time step.<BR>We are not 100% sure if we can calculate something useful this
way, but for small step sizes we hope to be lucky.<BR> <BR>However my first
question concerns the passing of a scalar field to getdp, i.E. a known
temperature field.<BR>This field needs to be used to calculate the conductivity
for each volume element. InterpolationLinear seems to not suitable for functions
with 3 parameters.<BR>Is there some way of defining a field using a linear array
and the number of the momentary volume element? <BR>Maybe something similar to
this fantasy-code:<BR>TemperatureField={0,0,0.1,0.2, .... } // for all finite
volumes<BR>T[]=Temperature[$NrMomentaryVolume]<BR> <BR>The second question
is about the state of the PETSc implementation. In an not so long ago post you
state that PETSc is working, but only on a single cpu. As a parallel solver
could be very useful to us, it would be great to have an rough idea in how many
months this might be ready for, well, lets call it
"field"-testing.<BR> <BR>Apart from this questions, I have an half finished
informal introdu<SPAN class=541510309-28042006>c</SPAN>tion to the weak form,
which only consists of a few pages in latex, written for those who hesitate to
read Bossavit. If you are interested in this, and want to read/comment it before
maybe spreading it to other people, I could finish writing it up within the next
two weeks.<SPAN class=541510309-28042006>
</SPAN>Although, I have to admit it might not <SPAN

greetings from <SPAN class=541510309-28042006>cloudy
