Hi everyone,

I’m working on an implicit analysis in LS-DYNA, and I’ve encountered the following error message:
IMPLICIT USAGE ALERT Memory Management for Implicit has changed after R10. Please use: memory= 10M
It appears that starting from version R10, there have been changes to how memory is managed for implicit calculations. The message suggests explicitly setting the memory allocation, but I’m not sure of the best way to implement this within my simulation setup.

Any insights or examples from those who have handled similar cases would be greatly appreciated.

Thanks in advance for your help.

Please set the memory using the suggested values in the alert. For example, if the mes0000 file shows below alert, try "memory=200m memory2=200m" in the ls-dyna command (for MPP solvers) or just "memory=200m" (for SMP solvers).  

A sample SMP command is: /path/ls-dyna i= input.k memory=200m
