Dear Libmesh team, I'm a beginner in computational science and c++ programming. So please excuse If I am not making any sense at somewhere.
I am trying to develop a structural mechanics solver for non-linear analysis problems. I don't have previous C++ experience and haven't used any C++ FEA Library so far. My requirements are following: 1. Input mesh reading. I prefer the Abaqus/calculix input format, which I hope, can be read by libmesh. 2. Data structure initialisation of node,element,Dof etc. 3. Derivation of Lagrangian interpolation functions from a polynomial at each node of the element. 4. Algebraic calculations on node variables and numerical integration on side of the elements. 5. Optimisation of a non-linear function of node variables, having linear constraints. Function value can be found by the value of variables. i.e not a blackbox function. Number of constraints are lesser than the number of variables. Objective function is differentiable. Previously I used Fmincon (Algorithm: SQP) in Matlab. Optimisation library interface should be simple. I hope NLopt may can solve my problem. It will be very helpful for me, if you direct me into the tutorials or give suggestions based on my above requirements. Thanks in advance ------------------------------------------------------------------------------ _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
