This ReadMe highlights important updates and known issues for the latest release of
Helius PFA, including
Advanced Material Exchange.

Updates
This section identifies important updates to the product.
- The
list of supported structural elements in
Advanced Material Exchange has been expanded.
- The curve-fitting routine for nonlinear material data characterization has been improved.
- Nonlinear material data no longer has an upper bound on the number of data points required per angle or environment.
- When you use the CNVTOL command in ANSYS 16.0, you must explicitly turn off the convergence criteria you do not wish to use. For example, if you wished to use only force convergence (as is often the case with
Helius PFA), you would enter CNVTOL,F, , ,0. In previous versions of ANSYS, this command would disable other forms of convergence. Now you must issue a separate command to turn off other forms of convergence. For example, you would enter CNVTOL,U,-1, , to turn off displacement convergence. Consult the ANSYS help for more details.
- Coefficients of thermal expansion are no longer set to zero for fiber-filled plastics with the linear elastic material model in
Advanced Material Exchange. This means that you can now perform a thermal simulation with both the linear elastic and elastic-plastic material models.
- Weak spring boundary conditions automatically generated by ANSYS Workbench are now supported.
- Advanced Material Exchange now allows you to import a mid-plane model from Moldflow that contains multiple sections or layers of varying thicknesses. Previously, if a study file contained layers with different thicknesses, a Thickness Discrepancy error would appear after importing into
Advanced Material Exchange. Now you can use the
layer controls in Moldflow to handle models with varying thicknesses.
Known Issues -
Advanced Material Exchange
The list below identifies the known issues in the latest release of
Advanced Material Exchange. Please contact Autodesk Support with any questions.
- Fiber-filled materials must have fibers with an aspect ratio > 1. The aspect ratio is measured as L/D, where L is the fiber length and D is the fiber diameter.
- Mapping results is not supported for structural assemblies. If your structural model contains an assembly with multiple parts, you will be prompted to select the individual part you wish to import.
- Moldflow Dual Domain elements are not supported. See the
list of supported element types for more information.
- Nonlinear material data is only allowed for the standard test angles of 0, 90, and 45 degrees.
- Nonlinear material data must have at least 15 entries per angle or environment.
- At least one data point on the nonlinear stress-strain curve must lie in the material's elastic region.
- Abaqus models that contain shell elements must have five section points through the thickness.
- ANSYS models that contain shell elements must have seven section points through the thickness.
- You cannot save an
Advanced Material Exchange project on a network server.
