    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Fosite - advection problem solver

    numerical simulation code for solving transport equations in 1D/2D/3D

    ...The method is 2nd order accurate in space and uses high order Runge-Kutta and multistep schemes for time evolution. In addition to the pure advection code several source terms have been implemented including viscous diffusion and gravitational acceleration. Fosite is written with object-oriented patterns in Fortran 2003 and follows the Structure of Arrays (SoA) layout, operating on generic field datatypes. This allows for high performance on modern architectures (SIMD). It is parallelized and vectorized. The software is thereby optimized for the NEC SX-Aurora TSUBASA Vector Engine .

    KoBra
    This is a standalone program for a) the calculation of diffusion coefficients of sorbates inside nanoporous materials at different loadings by using transition rate constants and for b) solving the master equation for a system consisted of a large number of unit cells per each direction. It is based on the following published paper "Kolokathis, P. D., Braun, O. M.. J. Comput. Chem. 2019, 40, 2053– 2066.

    OFR Analysis Tool

    For the analysis of output data from the OFR method

    The OFR method is a type of steered molecular dynamics method for determining potentials of mean force (PMF) (Phys. Rev. E, 2011, 83: 021114) and local diffusion coefficients, D(z) (Phys. Rev. E, 2012, 86: 036707). OFR-AT is a fast and convenient program for analyzing large output data files from the OFR method, and returns the information necessary to quickly and easily calculate the PMF and D(z) in a spreadsheet. The software is described in detail in the following article: J. Comp. ...

    rebind

    Lattice simulation of biochemical reactions and diffusion

    ...Motivated by several biological examples, we study the behavior of covalent modification networks when the activating component is localized to a planar membrane in either a random or clustered configuration. Reactions and diffusion are implemented on a three-dimensional lattice.
