<DIV><FONT color=#000000 size=2>Hello,</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT size=2>1) I still need surface integral (line integral in 2D in
fact).</FONT></DIV>
<DIV> </DIV>
<DIV><FONT color=#000000 size=2>I tried something like</FONT></DIV>
<DIV><FONT face="Courier New" size=2>
<P>{ Name Ampere ; Value { Integral { [ nu[] * {d a} ] ; Integration I1 ; In
Dirichlet_a ; Jacobian Sur ; } } }</FONT></P>
<P><FONT face="Courier New" size=2><FONT face=Arial>in the postprocessing and
get a :</FONT> Unknown Jacobian Method : Sur ...</FONT></P>
<P><FONT color=#000000 size=2>What is wrong with it ?</FONT></P></DIV>
<DIV><FONT size=2>Integral on submanifolds are extremely useful and even
necessary in some cases. What is available in GetDP on this today ?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>2) By the way, this kind of integral require the concept of
trace e.g. tangential component of a 1-form and normal component of a 2-form.
How is it dealt with in GetDP ?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>3) I did not see the dot product (scalar product) among the
operators (except its implicit use in the Galerkin command). Has it been
forgotten ? As the exterior derivative d is available as a short cut for grad,
curl, rot what about an exterior product Wedge[form1,form2] and/or an
explicit Hodge star operator ?</FONT></DIV>
