There are many types of hardware that will allow you to use Autodesk Nastran In-CAD. Proper choice of hardware however, can often make the difference between frustration and productivity. Here are a few suggestions:

  • Add more memory (RAM) above the minimum configuration. This will allow you to specify more memory for the Autodesk Nastran In-CAD and reduce the likelihood of memory thrashing (excessive paging of virtual memory to disk).
  • Required hard disk space is difficult to estimate, but in general you will never have enough. This is especially true when running large models. If you are continuously running out of disk space, you may want to invest in a larger and faster hard disk. Disk compression software may also help, but may also degrade performance.

What’s New in V2019.2 (October 2018)

Frictionless constraint

Frictionless constraints are applied to prevent surfaces from moving or deforming in the normal direction. You can apply frictionless constraints to both flat and cylindrical surfaces in a part.

GUID E5E0415C A9CC 4C0C 9DB6 DC91EE90E9BE 9727831

When applied to flat surfaces, frictionless constraints mimic the behavior of symmetry boundary conditions. However, unlike symmetry constraints, frictionless constraints do not require the setup of a local coordinate system for surfaces that are not aligned with the global coordinate system. As a result, frictionless constraints provide a quicker solution for establishing symmetry on angled and flat surfaces—especially for larger, more complex models.

Shrink Fit contact types

GUID B12EFABD FB17 4346 B5FC C6F111E883F7 3907019

Nastran In-CAD has two new contact types for non-linear analysis:

  • Shrink Fit / Sliding is used for a surface contact with initial interference between the contacting parts, where sliding is permitted.
  • Shrink Fit / No Sliding behaves like a Separation/No Sliding contact, but with initial interference between the contacting parts. Use this option when the intensity of fit and friction are great enough to prevent relative motion (sliding) between the contacting parts.

Meshing improvements

The meshing process has been made more efficient in 2019.2, especially for shell and solid meshes.

What’s New in V2019.1 (July 2018)

Stress Linearization

This utility graphs specified stress tensors along a Stress Classification Line (SCL) that you define. The stress tensor directions are based on a local coordinate system dictated by the two endpoints of the SCL and a third point that you specify. In addition, the Stress Linearization utility determines the primary membrane stress (Pm) and primary bending stress (Pb) that comprise the total stress (Pm + Pb).

Pin Constraints

Apply surface pin constraints to cylindrical surfaces to prevent the surfaces from moving or deforming in combinations of radial, axial, or tangential directions.

GUID F0155039 096B 4273 9A79 495B722BD326 2596731
GUID 24668A9C 5939 4319 B6D8 A31BAC9AEA39 7505487

Signed Stress Option for Multiaxial Fatigue

The Signed Stress option specifies whether the stress/strain used in the life calculation method in Multiaxial Fatigue analysis should be signed. When set to Yes, the sign of the invariant is determined based on the principal stress/strain. When set to No or Auto, the invariant stress/strain is always positive.

Autodesk Nastran In-CAD 2019

New Features

  • Mesh Improvements for Shell Meshes: All unstructured meshing modules now support the generation of cubic Serendipity elements, or elements with 2 mid-side nodes. There are also enhancements to the robustness of tri and quad surface meshing.
  • Bug Fixes: This release includes a number of bug fixes for issues that existed in previous versions of Nastran In-CAD.
    • Previously, contour plots of shell models that have the same top and bottom value were displaying correct results for one side of the element, but 0 for the opposite side. Now the contour plot properly displays values for the top and bottom side of the shell.
    • Autodesk Nastran In-CAD 2019
    • Previously, when you tried to create an XY plot that included non-zero strain data, the strain was incorrectly plotted as zero. Now, the strain data is plotted correctly.
    • Autodesk Nastran In-CAD 2019
    • Previously, the mesh convergence error was reported with units. Now, the mesh convergence error is correctly displayed with zero units.
    • Previously, the Frictional Stiffness for Stick input for surface contact was labeled with length units. Now, the input is correctly labeled with force/length units.
    • Autodesk Nastran In-CAD 2019
    • Beginning in Nastran In-CAD 2018, you could not select multiple items in the browser. This issue has been fixed so that you can now select multiple items using the Shift or CTRL key on your keyboard.
    • Previously, when modifying the modal analysis setup with the Fetch option for the modal database with the mdb file generated by Nastran In-CAD, the S1051 error occurred. This issue has been resolved.
    • Previously, when modifying the modal analysis setup with the Store option for the modal database, the user specified mdb file is not saved. This issue has been resolved.
    • Previously, units were displayed for the Failure Mode, Failure Index, Weld Surface Strength Factor, AME Damage State, and Matrix Effective Plastic Strain for the Advanced Material Exchange results. Now these results are correctly displayed without units.
    • Autodesk Nastran In-CAD 2019
    • Previously, PSD results for a random response analysis were displayed with incorrect units. Now all PSD results are displayed with correct units.
    • Previously, when you create a multi-axial fatigue analysis that uses strain-life inputs, if you edit the material after supplying the E-N data, the fatigue button does not indicate that the fatigue properties are entered. This issue has been resolved.

Autodesk Nastran In-CAD 2019

New Features

  • Advanced Material Exchange: Use Nastran In-CAD to import a structural input file generated by Advanced Material Exchange. After the file is imported, you can solve to simulate the as-manufactured model. This workflow allows you to simulate the changing fiber orientation distribution and the nonlinear material response in order to predict rupture in the fiber-reinforced material. Refer to the Edit topic for more information about importing the structural model or perform a tutorial using Advanced Material Exchange.
  • Mesh Settings dialogs have changed. In the main dialog you can now set Element Size by entering a numeric value, as before, or by using a slider with a range from Coarse to Fine.guid-e64ec96a-bea6-4694-a466-310f25d1a93c-8080477The Tolerance setting has been moved to the Advanced Mesh Settings dialog, which you can open with the Settings button on the main Mesh Settings dialog.guid-b65fdb42-fe52-45b2-960b-2ff6883aebb3-7194288
  • Grounded Spring Connector is now available, for attachment to a single endpoint.guid-4759828c-2762-4766-b6f3-3ca67f53085f-7151588Another change to the Connector dialog for Spring connectors is the Advanced Options button (middle column) to display or hide the fields for Stress/Strain recovery coefficients, Stiffness, and Damping.
  • Blue Text Warnings in the Nastran Output. These formerly displayed in red text. Now only fatal errors display in red.guid-7f5e175a-955f-4a0c-be84-075599be95c8-6313778
  • Symmetric Contact is now the default Penetration Type for all Surface Contacts, whether they are created manually or automatically. The figure below shows the setting on the Surface Contact dialog.guid-125759b4-a8aa-4c0d-bf39-0e9353cd824f-7636507
