The ALADDIN software package is still in development. Here is a list of software limitations and bugs that we know about:
[ Matrix Library ]
[ Finite Element Library ]
If you find a programming error, or a component of the software that has not been implemented (and should have been), please let us know by sending E-mail to austin@isr.umd.edu.
PrintMatrixCast ( A, [cm]);where the units conversion is a built-in name. We need to extend the language so that commands of the type
PrintMatrixCast ( A, [cm/sec/sec] );will also work.
stiff = Stiff();ALADDIN will return a global stiffness matrix stored in skyline storage. We currently assume that the stiffness matrix will be symmetric (although some applications will lead to non-symmetric matices).
stiff [2][1] = 10^10 N/m;Assignments of this type are not supported because they will destroy the matrix symmetry.
We are currently adding these functions to the plane stress/plane strain elements.
If you decide to add/fix some of these features, please e-mail austin@isr.umd.edu, and we will get you the appropriate code to work on.
