Abaqus Large-Scale Models: Practical Limits on Nodes, Elements, and Degrees of Freedom

Hello,

When working with large-scale models in Abaqus/Standard or Abaqus?Explicit, I would like to know whether there are any internal limitations on the total number of nodes or elements, particularly those related to memory allocation (arrays, connectivity tables, etc.), both during preprocessing (pre.exe) and during the solution phase (Abaqus/Standard or Abaqus/Explicit).

The official documentation specifies a maximum value of 999,999,999 for node and element labels; however, it does not clearly state any practical or theoretical limits on the total number of nodes, elements, or degrees of freedom in a model.

I am already aware of the potential limitations related to available memory. My question specifically concerns an HPC cluster environment with large available memory, where such constraints are not the primary bottleneck.

Additionally, a 3DS blog mentions that the 3DEXPERIENCE platform can handle models exceeding 200 million degrees of freedom. I would appreciate clarification on how this relates to Abaqus solvers in practice.

Could anyone please provide guidance or references regarding these limitations?

 

Best regards,
