This course will be instructing students to work on Autodesk® Nastran® In-CAD software which is a finite element analysis (FEA) tool embedded as an Add-on in Autodesk® Inventor® software. It acts as a tool for predicting parts or assembly behavior under various boundary conditions and mainly used by designer and analysts.

Topics Covered

  • Autodesk Nastran In-CAD Activation and navigation for conducting FEA analyzation on part and assembly models.
  • Creating, editing, and assigning idealizations and materials for using them in an analysis
  • Management of creation, setup, and modification of subcases that are being used for analyzing both static and dynamic models. some analyses types covered in this course: 
    • Linear Static
    • Nonlinear Static
    • Nonlinear Transient Response
    • Normal Modes
    • Direct Frequency Response
    • Modal Frequency Response
    • Direct Transient Response
    • Modal Transient Response
    • Random Response
    • Shock/Response Spectrum
  • Creation of constraint and assigning them to entities in the model
  • Creating loads which will exactly represent the magnitude and location of loads in real-world environment.
  • Creating Connector elements for simulation of how a physical connector will affect the model
  • Creating Surface Contact elements for defining contact between interacting components in an assembly.
  • Assigning local and global settings of mesh
  • Running an analysis of Autodesk Nastran In-CAD
  • Make imperatives with the required degrees of opportunity and dole out them to elements.
  • Make stacks that precisely speak to the greatness and area of the heaps the model will involvement in the workplace.
  • Make Connector components to mimic how a physical connector, for example, a bar, link, spring, inflexible body, or jolt will influence the model.
  • Make Surface Contact components to characterize contact between connecting segments.
  • Allot worldwide and neighborhood work settings.
  • Run an Autodesk Nastran In-CAD examination.
  • Survey and make plots for investigating the outcomes.
