FreeFEM v4.14

[4.14] (develop version 6/7/24)

For download of binaries (Linux, Mac and Windows) scroll down a little bit to Assets

Added

• Finite element BDM2 and BDM2ortho in test, Bug in BDM2ortho corrected the 4 sept 2014 in version: v4.13-130-g1af52457
• Conversion of matrix or transpose of matrix in int[int][int] array to get the structure of sparse matrix.
  see tutorial/sparse-matrix.edp example at end

  matrix A = va(Ph,Vh);
  int[int] a = A, at= A';
  

• a meshL finite function can be see as real function with 1, or 2 parameters

   meshL ThL = segment(10); fespace VhL(ThL,P1); VhL u= x;
   cout << u(0.5)   << endl;
   cout << u(0.5,0) << endl;
  

• Exemple to code convolution of 2 function with one with a small support
  too be not to expanxive
  see tutorial/Convolution-Sample.edp example
• Support for dense blocks in PETSc matrices
• GenEO for saddle-point examples with PCHPDDM in PETSc
• Distributed ParaView output on meshS
• Interface to mmg2d for two-dimensional mesh
• Support for Mmg parameters localParameter, -nosizreq, -hgradreq`

Changed

• PETSc 3.20.2

Deprecated

Removed

Fixed

• bug in P3pnc3d in vectorial case (thank to loic.balaziatchynillama@cea.fr )
• in segment(10,region=1,label=ll); region is now used..

Sorry the ARM version (Apple-Silicon) was wrong before due to mistake in brew library
(need to install brew gfortran), the develop version (06/07/24, FreeFEM-v4.14-60-g660dbd36-Apple-Silicon-O.dmg) is correct on Mac M2 (almost all test are OK).

The new Mac version (develop) works after security authorization (see README.md)
(see the small moving https://www.youtube.com/watch?v=SEF4PAkR51g to understand howto do )
if you do not succed please
send me a Mail to: frederic.hecht@sorbonne-universite.fr.

Remark: The dev file or with name --g*.dmg are the current develop version.
