The phrase alludes to a common problem encountered when using the INCLUDE directive within the pre-processing stage of LS-DYNA simulations involving Dual-Core (or Dual-CPU) parallel processing. The INCLUDE directive’s function is to incorporate external files containing model data. When this functionality fails, the simulation setup is compromised, preventing the intended parallel execution. For instance, an error might arise if the included file’s path is incorrect, the file is corrupted, or there’s a mismatch in data structures between the main input file and the included file. This results in a pre-processing failure, halting the entire simulation before the actual computation begins.
Correctly functioning INCLUDE directives are crucial for efficient and accurate LS-DYNA simulations, particularly those leveraging parallel processing. They enable modularity, facilitating the management of complex models by breaking them down into smaller, more manageable parts. This approach reduces development time, improves code readability, and streamlines debugging. Furthermore, robust INCLUDE functionality is vital for the repeatability and reliability of simulation results. Errors in inclusion can lead to inaccurate or inconsistent outputs, potentially jeopardizing engineering designs and analyses. Historically, issues with INCLUDE directives have been a recurring challenge, prompting ongoing improvements in LS-DYNA’s pre-processing capabilities and associated documentation.
This issue necessitates a detailed examination of several critical areas: verification of file paths and data integrity, understanding the intricacies of the INCLUDE directive within the context of Dual-Core processing, and exploring effective troubleshooting strategies for resolving such pre-processing errors. A comprehensive analysis of these elements will guide users toward improved model construction and successful execution of parallel LS-DYNA simulations.
