[Getdp] Simple constraint question

[sdurand]

Hello,

Is there an easy way to initialize both the value of a field and its
time derivative (eg to solve hyperbolic problems) using the
Constraint{ ..., Type Init,...} command?

A standard boundary condition for 1-forms is to prescribe the tangential
trace nxu = g. How is this implemented in GetDP?

Thank you!
