Ey, thx for the explanation, this really helped me with setting up the K-matrix. I do have 1 question though, at 46:15 when you construct the 'F' vector. I dont really see how you get [0 u 0 -u]. Did you make an assumption that u3 should be 'u' (since u3 is connected to u4, which obviously makes sense) ? Or did you actually calculate these numbers?
Nice and crisp intro on XFEM. I liked it

Really bad teaching one can read the slides oneself
