What guidelines should I follow for simulation software projects?
"developers lack the skills".
Maybe.
I think it's much more likely that the developers lack the incentives. Making solid code is difficult and expensive and, in academia, comes with minimal-to-...

What guidelines should I follow for simulation software projects?
I maintain (and am the main coder of) a simulation software that has been developed for ~8 years and is used by few hundreds people. It all started as a side project during my PhD, and it clearly ...

What is the fastest opensource implementation of Bessel functions computation?
The appropriate and fastest library depends on several things. Which Bessel functions (only J, Y & Hankel or modified Bessel functions I & K too), for which types of arguments (real or complex,...

fastest linear system solve for small square matrices (10x10)
Using an Eigen matrix type where the number of rows and columns is encoded into the type at compile time gives you an edge over LAPACK, where the matrix size is known only at runtime.
This extra ...

fastest linear system solve for small square matrices (10x10)
Another idea could be to use a generative approach (a program writing a program). Author a (meta)program that spits out the sequence of C/C++ instructions to perform unpivoted** LU on a 10x10 system.. ...

Fluid-structure interaction solver for cardiovascular applications
People typically agree that the monolithic approach is the conceptually better one, but of course more difficult to implement.
If you want to use a code that already does most of what you need, I ...

What is the fastest opensource implementation of Bessel functions computation?
This is really going to require some testing with regards to speed, but here are some examples I remember coming across that aren't Boost or GSL:
A wrapper of the Fortran routines by DE Amos is here ...

fastest linear system solve for small square matrices (10x10)
Your question leads to two different considerations.
First, you need to pick the right algorithm. Hence, the question if the matrices have any structure, should be considered. E.g., when the matrices ...

What guidelines should I follow for simulation software projects?
tl;dr: Look outside our field, start by following the Linux Foundation Core Infrastructure Initiative Badge guidelines and then maybe also have a look at the xSDK policies for HPC simulation software.

I would try blockwise inversion.

Open source FEM implementation for Windows
I would suggest OpenSees: http://opensees.berkeley.edu/index.php. Some colleagues in my department made fairly good use of it a couple of years ago in combination with SAP2000.
