I'm currently implementing a blow-up problem with space-time adaptivity controlled by a derived pointwise a posteriori error bound and I'm having trouble implementing the estimator (previously, I just used meshworker and it did most of the work for me but you cannot use such an approach for pointwise spatial estimators). I've got it correctly looping over cells and also got it looping over all faces and correctly calculating the value of the estimator on the *boundary faces*, however, I'm not entirely sure how if I'm on a given face in a given cell I can obtain the values I need from the neighbouring element. In particular, I'm not sure how to locate the neighbour (I think once I have it I can work over it with FEFaceValues without any issues!). I'm sure the answer is obvious but I just can't find it.
Thanks for any help!
