  • Infrastructure and application monitoring for Azure Infrastructure and application monitoring for Azure Icon
    Infrastructure and application monitoring for Azure Icon

    Monitor your Azure® infrastructure, application, and systems performance side by side in a single enterprise-monitoring tool

    So, you moved your applications and servers to Azure, but are they running any better and are you able to justify the investment? Without proper monitoring, you’re left guessing if application and server performance has improved, and when issues arise, you’re left scrambling to locate the root cause. SolarWinds® Server & Application Monitor (SAM) can monitor your Azure workloads side by side with your on-premises workloads to help ensure optimal application performance.

  • MF-OWHM | MODFLOW OWHM Icon

    MF-OWHM | MODFLOW OWHM

    Simulation, analysis, and management of the movement of water

    Please see the “Files” link above to download different versions. The One-Water Hydrologic Flow Model (MODFLOW-OWHM, MODFLOW-ONE) is an integrated hydrologic flow (IHM) model that is an enhanced fusion of multiple MODFLOW (MF) versions. While maintaining compatibility with existing MF versions, MF-OWHM includes: linkages for coupled heads, flows, and deformation; facilitation of self-updating models, additional observation and parameter options for higher-order calibrations; and redesigned code for faster simulations. MF-OWHM represents a complete IHM that fully links the movement and use of groundwater, surface water, and imported water for consumption by agriculture and natural vegetation on the landscape, and for potable and other uses. This provides the foundation needed to address integrated hydrologic problems such as evaluation of conjunctive-use alternatives, sustainability analysis, including potential adaptation and mitigation strategies, and best management practices.

  • NKA

    Nonlinear Krylov acceleration of fixed-point and Newton-like methods

    Nonlinear Krylov Acceleration (NKA) is a method for accelerating the convergence of fixed-point (Picard) iterations. Many Newton-like and inexact Newton methods are fixed point iterations. The NKA project provides the canonical implementation of the method for several programming languages. The black-box accelerator is simple to integrate into existing code. Placed in the iteration loop, it observes the sequence of solution updates and replaces them with improved updates using information it has gleaned from previous solution iterates. It was only recently recognized (2011) that NLK is essentially equivalent to Anderson Acceleration for a specific choice of mixing parameter. NLK was independently devised in the late 1980's using a very different approach, and though it leads to the same algebraic method, NLK's organization is somewhat different, and arguably superior. The NLK approach also provides clear rationale for the proper choice of Anderson's arbitrary mixing parameter.
