I'm trying to do a LPBF additive manufacturing simulation using Inherent Strain. When I activate the "Scan Pattern" option in "Inherent Strain Defenition" and run the model, I get this error:

Failed to read AM strain shrinkage data.

What am I doing wrong?

The error message could be related to issues with the AMResults.txt file where the data for Structural AM analyses is written. This file includes the z-deformation of a layer just before a new layer is applied and is crucial for identifying potential issues when spreading a new layer. If the software is unable to read this data, it could be due to problems with the generation or saving of the data during the simulation process, or issues with accessing the AMResults.txt file correctly. To resolve this, you should check that the simulation is set up to generate this data and that the file is not corrupted or inaccessible.
