comment Error in the solving of the simultaneous Ordinary Differential Equation
one way would be to differentiate the last equation and use it to eliminate the second equation. Then the question would be are the first and the new second equation compatible?

@MichaelE2 yes you are right. I had corrected it but not online :-)

@Szabolcs what do you suggest? Its a bug with an easy workaround?

your answer is useful for people who are happy with DiscretizeRegion. According to @user21 I need ToElementMesh in order to be able to solve a PDE on it.

comment How to specify PDE Boundary condition on Bspline?
@user21 I found a workaround: this works: Jet0[{{1, 0}, {18, 18}/10, {0, 2.2}}] !

@user21 The mesh seems to fail relatively systematically, e.g. for {{1, 0}, {1.8, 1.8}, {0, 3}}. Would you have a workaround? I have updated this question mathematica.stackexchange.com/q/89166/1089 with the pb.
