Hello ANSYS community,

I need assistance with my ANSYS Workbench AM DED simulation, which consistently crashes after running for hours. Is there a way to save and resume simulations at specific points? Any guidance or tips would be highly appreciated.

Thank you,

Pouyan

Hi Pouyan,
Do you get any errors when your model crashes? Do you face this crashing error with every model or with the specific model only?
Have you tried to clear the %appdata% and change the name ".Ansys" in the %temp% file? I have seen that some users have resolved this type of issue by resetting the ansys through %appdata%.
Does the mechanical window close after crashing or does the WB window also close?

Regards,
Sampat

Hi Sampat,

No, I haven't encountered any errors. However, after a certain period, the mechanical window stops responding, prompting me to close and reopen it from the Workbench window. To provide you with more details, I initiate the AM DED simulation to obtain temperature solutions. Since I require temperature data for each timestamp in my transient analysis, I create a resultbase for each timestamp. Everything proceeds smoothly up to this point. However, when I attempt to retrieve the solution for all timestamps, which can reach up to 30,000, ANSYS crashes when dealing with a high number of timestamps but functions properly with a lower number, such as in lighter simulations.

I'm unsure about how to clear the %appdata% and change the name ".Ansys" in the %temp% file.

P.S. It appears that the process of extracting transient data may not be the most efficient one, but it's the method I've learned from this forum. Please let me know if you have an alternative approach.

Best Regards,

Pouyan

Hi Pouyan,
I appreciate your patience. 
For clearing %appdata% you can follow the attached link
https://featips.com/2022/02/11/when-all-else-fails-reset-appdata/#:~:text=Here%20is%20how%20you%20can%20reset%20ANSYS%20Appdata%3A,v211_Old%207%20Launch%20ANSYS%20and%20refresh%20the%20project
for %temp%- follow the same method and rename the .ansys to .ansys_old

For the other queries, I think it might be an issue while extracting results up to a large extent of 30,000 timestamps. Do you use the Ansys student version ( Free version)? Are you facing this issue with other system or other Ansys version too? Have you checked the graphics card updated or not? Please let me know.
