Residual strain and fiber orientation

[iurrutiaRKHVZ]

Is there any possibility to import a residual strain and fiber orientation from a Moldflow study to Inventor Nastran?   I have seen a document published in Autodesk University in 2017, it was called: " All for Composite Simulation as Manufactured: Autodesk Nastran, Helius PFA, and Moldflow Ecosystem"   But it is required Helius PFA software. Nowadays, does it remain as in 2017? with the necessity of the three softwares or  has this fact changed?   So, is PFA still needed? In the positive case, is it possible with Helius PFA 2019 and Inventor Nastran 2022?   In negative case, which is current way to pass residual strain and fiber orientation from Moldflow Insight to Inventor Nastran?

Hello iurrutiaRKHVZ,

I am only familiar with the Moldflow - Helius - Nastran approach and I recently completed this with Moldflow Insight 2021.2, Helius Advanced Material Exchange (AME) 2021.1, Helius PFA 2021.1, and Inventor Nastran 2022.  As per the Helius 2021.1 What's New - this version would support Inventor Nastran 2022.

Hello mason.myers,

Thank you for your answer.

I have another doubt about the use of this 3 softwares. According to the next photos, do I have my analysis in Nastran correct?

After simulate the injection in Moldflow, and mesh the part in Nastran. I opened both in Advanced Material Exchange and then I exportes to structural package.

I import this structural model to the Nastran analysis.

And I have a doubt because the characteristics I see on the material properties are this ones:

I am not sure if the material properties have been correctly imported with the structural package.

Do you know something about this fact?

Thank you

Looks good to me, here is an Inventor Nastran Tutorial that highlights the workflow.  From what I can see, it appears that you are taking the correct steps.

The last time I did this, I had to run the updated .nas file from the Nastran command line to prevent some errors from occurring.
