The error message says “Sorry, no jump, mean, otherside in bilinear term must be in integral of type intalledges, intallVFedges or intallfaces”. Indeed you cannot use “jump” in an “int1d” term.

Thus in the int1d you have to put explicitly what you mean by jump(u). Is it just “u” (value from the inside of the domain) ?
