Dohyun Kim f67f1fccf7 Fix 1-d bug! 
As MFEM positive/negative elements ordering
does not respect the original mesh ordering,
normal vector can be positive or negative in 1D.
We check this by checking integration point is either right or left for 1D.

Dohyun Kim 2d6c70186c update burgers equation 2023-03-02 13:05:55 -05:00
Dohyun Kim 07eb581bec Finalize update functionality. Visualization not yet implemented. 
Tested with derefine and refine after system construction.
Current code seems to give correct result.
May require further verification.
 2023-03-02 12:33:45 -05:00
Dohyun Kim 629a3bc4ad Update method included for HCL. 
It is not tested yet.
Also, since Operator does not have Update method,
we needed to restrict Operator to NonlinearForm

Dohyun Kim 8677d3bdad correct errors in euler flux functions 2023-02-27 17:30:34 -05:00
Dohyun Kim db9c5867d6 default periodic square mesh updated 
it seems that 2x2 periodic mesh does not work.
-> This is because 2x2 contains both 0->1 edge and 1->0 edge on the boundary
due to periodic constraint.
I believe that is why 3x3 elements are used in the data folder.
