Inventor 202 does not release memory

[Anonymous]

Inventor 2020 is ramping memory and then never releasing it, even after all the files are closed (the files/occurrences count is 0/0). It seems that Inventor would only take what it needs, but as it takes more and more, it becomes less able to handle its own mess.  Constraints go wacky in both sketch and assembly. Inventor crashes at odd times, but the issue is occasionally repeatable.  The update that was just put out doesn't seem to address the issue.

Is anyone ELSE having this issue?

Recommend you to move this from Inventor Customization Forum (focus on Inventor API and iLogic issues)to Inventor Forum to get more response.

I Have simmilar issue which shows up with using API.

I'm trying to do mass file generation based on ilogic driven assembly and model. Code running in assembly would iterate through all possible combination of 2 parameters (nested  "For" loop) generating new assembly, new drawing and generating PDF and STP. Code would close generated files before generating new ones. Unfortunately Inventor does not clear memory used and it would grow until crash (roughly after ~100 iterations).

API option to purge Inventor memory would be usefull in such situations

I agree if API can help to release memory would be useful, can you share a code sample to reproduce the memory leak issue? We can look into it further.
