lipnikov added a screenshot of anisotropic mesh minimizing interpolation error -
ani2d ani2D-2.2 file released: user_guide-2.2.1.pdf
* Version 2.2.1 was released - fixed an error in assembling Raviart-Thomas mass matrices - fixed wrong pointers to groups of unknowns in assembling rectangular matrices. - fixed a bug in imposing boundary conditions for hybrid mixed FE test case. - rewrote python package to make it more transparent * Version 2.2 was released - added StokesNavier (lid driven cavity) to Tutorials/MultiPackage - added package aniINB for inexact Newton-Krylov backtracking nonlinear solver - removed unnecessary scaling when there are no curved edges - added prefix ANI to internal constants defined in magic.fd - added the ZZ recovery method (a simplified version of the L_2 projection method) - increased size of numeric(2) and symbolic(2) in F77 wrappers for 64-bit machines - added a Laplacian mesh smoothing - code cleaning and documenting
