| Jun 27, 2020 at 15:51 | comment | added | Almendrof66 | Thank you a lot for your explanation, Could I please ask you another question, I'm trying to calculate the value of $u$ at the node $a_5$ which is $(\frac{1}{2},\frac{1}{2})$, but after all my attempts using the local basis function I get a singular matrix, could you please give me indications on the process. Thank you in advance | |
