Product Life-cycle Management (PLM) Performance Work Statement Amendment 02

NASA has identified Model Based Engineering (MBE) as a key Digital Transformation capability to improve quality of designs, reduce risks, improve schedules, and reduce costs.

Consistent with these Agency objectives, the MSFC Engineering Organization requires the capability for a Model Based Engineering (MBE) environment for design, analysis, simulation, and manufacturing. A complement of tightly coupled products and services is required to achieve the desired model associativity and efficiencies provided by an integrated design suite of tools.

MSFC MBE Environment Requirements:

1. The MBE environment shall be designed specifically to manage models in the existing and proposed Engineering application suite with limited custom or third-party integrations

2. The common modeling environment (CME) will be compromised of an integrated set of existing and future repositories, including a Product Lifecycle Management (PLM) tool to manage the interoperable tool set. The CME will accommodate 70 PLM users either authoring, reviewing or consuming functions scalable to 250.

3. The CME shall provide high-end PLM functions:

a. Manages tightly integrated engineering data at model level to include design, analysis, manufacturing and operation and associated meta data at the start with configuration and change management with minimal set up out of the box.

b. Provides access to all consumers to the single authoritative model; single source of truth

c. Provides configuration and change management

d. Provides engineering and manufacturing workflows (configuration to be required after the fact based on requirements we will give at that time).

e. Enables collaboration among different engineering disciplines during in-work development and during structured processes like PDR, CDR, DCR.

4. Any proposed PLM should be capable of managing the data and actively and automatically propagate any changes across existing and proposed Engineering application suites . The PLM shall be immediately updated as needed to accommodate the latest versions of the Engineering application suite as they are released.

5. Any new PLM shall be capable of integrating with our current PLM-ICE Windchill- either directly or via third-party tool. Some level of configuration may be required, but if so it should be minimal. The method, approach, and level of effort, for such integration will be a factor in evaluation of such solution.

6. The core tool set shall maximize interoperability/associativity between tools. Specifically, the Mechanical Computer-Aided Design (MCAD), Electrical CAD (ECAD), stress & thermal analysis, Computer-Aided Manufacturing (CAM), Additive Manufacturing (AM), and Operations Simulation models shall all reside in the CME/PLM. Design changes shall propagate across all disciplines automatically, without need for manual processes. Meaning that a master digital model drives all associated engineering development and changes at model level

7. .Initially, the core set shall include a primary CAD, structural & thermal analysis, ECAD, CAM, Additive Manufacturing, and an Operations/Manufacturing simulation tool. In later phases, the tool set should be able to scale to include all other disciplines like systems, fluid dynamics, etc.

8. NASA/MSFC Core tools that we are currently using and are not open to changing:

MentorGraphics ECAD, NX NASTRAN, Femap, Process Simulate Human, and Fibersim. CAD, structural & thermal analysis, CAM, AM, and Operations tools shall be chosen to work with the latest software versions of these tools per the interoperability requirements.

9. RESERVED

10. Additional CAD tool requirements:

a. Support high-end Model Based Design (MBD) Product Manufacturing Information (PMI) capability, including export to 3D Portable Document Format (PDF)

b. Support integrated AM and topology optimization tools and Generative Design

c. Export CAD design data into multiple formats including the latest common neutral formats: STandard for the Exchange of Product (STEP), Initial Graphics Exchange Specification (IGES), and Jupiter Tessellation (JT)

11. Additional thermal analysis requirements:

a. The tool shall provide a space thermal capability, including capability to generate on-orbit environments (view factors to space/vehicle). The ability to calculate solar, albedo, nor IR fluxes when in an orbital space environment and provide planetary surface environments.

b. Ability to import Printed Circuit Board design data directly from Mentor Graphics into the analysis tool

c. Can provide 1-d fluid system modeling for simplified fluid modeling. This is integral to most of the tools MSFC uses to model Environmental Control and Life Support Systems and active (pumped) fluid models. The tool shall simulate a pumped fluid loop and the heat transfer to/from thermal hardware. The tool shall also provide a means of determination of pressure drop and mass flow essential to size pumps, valves, etc.

d. Can update model by opening and editing in Excel directly primarily to perform parametric studies. Update parameters and re-execute the model for a given solution set.

e. Can use simple conditional logic in fields (no FORTRAN input files, or codes needed)

f. Can map (show results) for individual parts at the assembly (integrated level).

g. Can map to multiple identical parts at once with no need to reposition due to being linked to the CAD

h. Position changes in general are maintained at the design level and Finite Element Model

(FEM) are repositioned automatically; benign to moderate changes in geometry can be updated from the CAD effortlessly and maintain thermal couplings with an automatically updated mesh

i. Has a command finder tool

j. Can show multiple views of varying results with the option of synchronizing viewports

k. The thermal analysis tool should be able to add additional features, solution methods, materials as the tool is developed. This could be considered typical maintenance and updates along with import capabilities (database of thermophysical and optical properties).

12. Additional structural analysis requirements:

a. Solver must support industry standard methods of solutions for numerical modeling

b. Allow design analysis solver flexibility options embedded in the pre/post processing tool for use by preference in the various engineering departments at MSFC: NASTRAN, ANSYS, or Abaqus

13. Additional CAM requirements:

a. The CAM model shall be associative and created directly from the CAD model

b. The Computer Numerical Control (CNC) toolpath shall be created directly from the CAM model

c. The CNC programming language, G-Code, file shall be generated directly from the CAM toolpath using an output post processor

14. Additional Additive Manufacturing (AM) requirements:

a. The AM tool shall provide capability for additive design, advanced lattice design, topology optimization, and additive simulationThe AM tool shall have direct integration features, including toolpath generation, for our existing manufacturing machines, including our specific ConceptLaserRP and EOSPrint machines

b. The AM tool shall have a direct integration with Materialise Magics AM solid object manipulation software; allows for use of existing Magics models

c. Specific features required are effective overhang, volume analysis, and channel diameter analysis tools

15. Additional Operations/Manufacturing Simulation requirements

The Manufacturing and Assembly software shall create and use lightweight models and load in at least 10,000 files. Some recent examples are: Case-1: 6,500 files (4GB), Case-2: 3,200 files (3GB)
