Framework System Design Description

Introduction

Many of the phenomena related to advanced manufacturing processes depend on the solutions of multiple physics models, which can be described by partial differential equations that provide spatially and temporally varying values of solution variables. These models for individual physics often depend on each other. MALAMUTE relies on the MOOSE framework to solve these physics models, accounting for the couplings that may occur between them. This document describes the system design of MALAMUTE.

System Purpose

The Software Design Description provided here is description of each object in the system. The pluggable architecture of the underlying framework of MALAMUTE makes MOOSE and MOOSE-based applications straightforward to develop as each piece of end-user (developer) code that goes into the system follows a well-defined interface for the underlying systems that those object plug into. These descriptions are provided through developer-supplied "markdown" files that are required for all new objects that are developed as part of MALAMUTE. More information about the design documentation for MOOSE-based applications like MALAMUTE can be found in Documenting MOOSE.

System Scope

MALAMUTE performs simulations related to advanced manufacturing (AM) processes. These models often include highly coupled systems of equations related to heat conduction, electromagnetics, Navier Stokes, mechanics, and surface morphology, amongst others. Material models are also included to support these simulations (such as graphite and stainless steel), and they themselves are often dependent on simulation variables: temperature, electromagnetic field strength, stress/strain, etc. While many models within MALAMUTE are performed at the "engineering scale" (i.e., at the scale of centimeters and meters), the MultiApp System can be leveraged to allow for multiscale coupling to the micro- and nano-scale of a given experiment. This allows for not only experimental process design and evaluation at the operator level but also evaluation of a process on the formation of a part and the experiment's end result.

In addition to modeling full experiments (like in electric field-assisted sintering (EFAS)), MALAMUTE also contains building blocks for use in larger manufacturing models or as individual studies, such as directed energy deposition and laser welding (with surface deformation and melting). Mechanics models for pressing procedures are also under development.

Dependencies and Limitations

MALAMUTE inherits the software dependencies of the MOOSE framework, with no additional dependencies.

Baseline: A specification or product (e.g., project plan, maintenance and operations (M&O) plan, requirements, or design) that has been formally reviewed and agreed upon, that thereafter serves as the basis for use and further development, and that can be changed only by using an approved change control process (NQA-1, 2009).

Design Stakeholders and Concerns

Design Stakeholders

Stakeholders for MALAMUTE include several of the funding sources including Department of Energy (DOE) and INL. However, Since MALAMUTE is an open-source project, several universities, companies, and foreign governments have an interest in the development and maintenance of the MALAMUTE project.

Stakeholder Design Concerns

Concerns from many of the stakeholders are similar. These concerns include correctness, stability, and performance. The mitigation plan for each of these can be addressed. For correctness, MALAMUTE development requires either regression or unit testing for all new code added to the repository. The project contains several comparisons against analytical solutions where possible and also other verification methods such as MMS. For stability, MALAMUTE maintains multiple branches to incorporate several layers of testing both internally and for dependent applications. Finally, performance tests are also performed as part of the the normal testing suite to monitor code change impacts to performance.

System Design

MALAMUTE relies on MOOSE to solve the coupled physics models underlying advanced manufacturing processes, accounting for the couplings that may occur between them. The design of MOOSE is based on the concept of modular code objects that define all of the aspects of the physics model. MALAMUTE follows this design, providing code objects that define specific aspects of the solutions for its physics that derive from the base classes defined by the MOOSE framework and the modules that it depends on.

MALAMUTE provides specialized Kernel classes that compute the contributions from the terms in the partial differential equations for heat conduction and electric current transport in an electric field assisted sintering apparatus; the heat conduction, fluid flow, and surface deformation of a melt pool and laser welding; and for simulating directed energy deposition (DED) processes. It also provides specialized Material classes that define the constitutive behavior of materials of interest for sintering, DED, melt pools, and the level set method. In addition, it provides miscellaneous BC and InterfaceKernel classes to facilitate various aspects of these simulations. Much of the functionality of MALAMUTE is provided by the MOOSE modules that it builds on.

System Structure

MALAMUTE relies on the MOOSE framework to provide the core functionality of solving multiphysics problems using the finite element method. It also relies on the MOOSE modules for much of its core functionality. A summary listing of the current modules required for complete MALAMUTE operation are shown below:

The structure of MALAMUTE is based on defining C++ classes that derive from classes in the MOOSE framework or modules that provide functionality that is specifically tailored to the structural degradation problem. By using the interfaces defined in MOOSE base classes for these classes, MALAMUTE is able to rely on MOOSE to execute these models at the appropriate times during the simulation and use their results in the desired ways.

Data Design and Control

At a high level, the system is designed to process HIT input files to construct several objects that will constitute an FE simulation. Some of the objects in the simulation may in turn load other file-based resources to complete the simulation. Examples include meshes or data files. The system will then assemble systems of equations and solve them using the libraries of the Code Platform. The system can then output the solution in one or more supported output formats commonly used for visualization.

Human-Machine Interface Design

The MALAMUTE application is a command-line driven program. All interaction with MALAMUTE is ultimately done through the command line. This is typical for HPC applications that use the MPI interface for running on super computing clusters. Optional GUIs may be used to assist in creating input files and launching executables on the command line.

System Design Interface

All external system interaction is performed either through file I/O or through local API calls. Neither MALAMUTE, nor the MOOSE framework, nor the MOOSE modules are designed to interact with any external system directly through remote procedure calls. Any code to code coupling performed using the framework are done directly through API calls either in a static binary or after loading shared libraries.

Security Structure

The MALAMUTE application does not require any elevated privileges to operate and does not run any stateful services, daemons or other network programs. Distributed runs rely on the MPI library.
