Abaqus internal error in package_dp

Symptom:
In large models, the following error may occur during package_dp (before the solver starts):

***ERROR: Abaqus/Explicit has encountered an internal error during the
***ERROR: analysis. Please report the issue to local office.

Cause:
A hard limit is hit on Abaqus memory buffer (the packager converts all the information in the input file into matrices, vectors, etc.)

Workarounds:
To reduce memory required:

• Reduce DOFs in model
• Change *equation constraints to *kinematic constraints
• Change “Surface to Surface” ties to “Node to Surface” ties

Also try:

• Run with Abaqus 2019+
• Increase SIN_CAP (os.environ[‘ABA_SINT_CAP’] = ‘16000’)

Solution:
Simulia is aware of the issue and is working to fix it in the next release

Start by reviewing the package_dp path and the Abaqus version and SIN_CAP conditions described in the issue. Check whether the repository has a controllable point for this pre-solver memory failure; no file or test is named, so done would require a maintainer-confirmed fix or documented limitation.
