Memory and Resource Management¶
Understanding Resource Use¶
Abaqus Data¶
Abaqus uses memory and disk resources during analysis. Understanding resource use helps optimize performance.
Requirements and Considerations¶
- Large models require more memory
- Parallel execution can reduce memory pressure
- Adequate disk space is essential for temporary files
Resource Management Parameters¶
Memory Management Parameters¶
input¶
Syntax: input = memory_specification
Description: Specifies the maximum amount of memory or maximum percentage of physical memory during input file processing.
Example:
memory¶
Syntax: memory = memory_specification
Description: Specifies the maximum amount of memory or maximum percentage of physical memory during the analysis phase.
Example:
Disk Management Parameters¶
scratch¶
Syntax: scratch = directory_path
Description: Specifies the directory for temporary files.
Example:
Input File Processing and Data Check¶
Guidelines for Memory Settings¶
When setting memory for datacheck analysis execution, consider the following factors:
- Number of elements and nodes in the model
- Element type and complexity
- Whether user subroutines are present
Typical Memory Settings for Datacheck Analysis¶
| Degrees of Freedom | Memory Recommendation |
|---|---|
| < 100,000 | 1-2 GB |
| 100,000 - 500,000 | 2-4 GB |
| 500,000 - 1,000,000 | 4-8 GB |
| > 1,000,000 | 8 GB or more |
Abaqus/Standard Analysis¶
Guidelines for Memory Settings¶
Setting Memory on Single-User Machines¶
For single-user machines, it is recommended to allocate 80-90% of physical memory to Abaqus.
Setting Memory on Multi-User Machines¶
For multi-user machines, adjust memory allocation based on the number of concurrent users and job requirements.
Setting Memory When Using Queues¶
When submitting jobs through a queue system, consider memory limits for queue jobs.
