I am wondering is there any robust, well-tested, accurate open source FEM solver package for Windows? I would like to use to power the engine of my structural engineering application.The FEM package should come withMeshing algorithmStatic solverModal AnalysisEverything that is standard for structural engineering applicationI don't need it to run on clusters, because my application should be able to run on personal laptops. I took a look at Code_Aster, but it is not supported natively on Windows. I can find a list of such packages at wiki, but I am not sure which one is alive and under development, and which one is a dead-end project.
