Hello everyone! Can I make an expression u(x) for 1D analytical solution, that can take *q_index* for evaluating u(@ *q_index*), while skip obtaining *q_index* locations/points value?
I am doing the residual: *u(x) - u_h(x)* under each cell, in which *u_h(x)* comes from approximation that has its basis function available for *q_index*. I do not worry about *weights and dx*, they are working together. However, if I cannot make the analytical solution u(x) to be under *fe*, how to let u(x) take *q_index* information? Thank you very much!
