<br>Probably a simple question but I can't find the answer in the examples of the wiki or searching the list.<br><br>I am trying to define a Robin type boundary condition for the Laplace equation on a cube<br><br>dphi/dz+constant*phi=0 on one face<br>
<br>I think the weak form of this is<br>integral_over_face(test_function * trial_function*constant) =0<br><br>can someone point me to an example of how to write this in the .pro file? <br>thanks<br><br>and thanks to Christian for his public spiritedness over many years by the look of the archives.<br>
