stack trace error #28

Open JSSPandi opened 1 month ago

JSSPandi commented 1 month ago

Hello. Thank you for making this tool to find out the various modes for the data generated using OpenFOAM. I compared the modes for Re=100 flow past cylinder and it is virtually the same as reported in numerous articles. I am facing an error when I use more number of snapshots like more than 250. The error is printed below:

Could you please give me suggestions? Thank you. Regards, Jawahar.

Jawahar,

I’m sorry, but Illinois Rocstar LLC has ceased operations, and there are no technical staff left to answer your question.

Best of luck.

@JSSPandi Could you tell me if you have 250 or more flow snapshots available to read in your case directory?

JSSPandi commented 1 month ago

Thank you for reaching out. To be exact, I have 329 snapshots.

akashaero commented 1 month ago

Okay. One more question. Do you have enough RAM to load all snapshots in memory?
