Taking long time to load the results

Post by Asad005 » Sat Jan 30, 2021 2:26 am

Dear stko team,
I run 2d model. It took about 18 hours to complete the analysis. but it is taking a very long time (more than 4 hours) in uploading the results in post-processor after opening the database. Only 72% of the results are loaded in more than 4 hours as shown in the attached screenshot.
Is it normal that it takes so long time or its because of some issue in my model.
Model is attached herewith for your kind consideration.
Thanks

Dear User,

Could you tell us how large your MPCO file is?

You have 5000 elements (that are not too much) but you saved a lot of results and for all time steps (144100). I still think that 4 hours to load them is not normal, but you can do something to decrease the size of the output file.

First, I had a look at your timeSeries. Are you sure you want all those cycles? Are they from an experimental test?

Another thing is that, when you have large databases , it's useful to store them into a SSD hard-disk rather then into a standard hard-disk

thanks for your kind response.
The size of the mpco files is shown in the attached screenshot.
The following statement is mentioned in the paper regarding displacement history:
"An increment of the imposed horizontal displacement every three cycles were considered in order to evaluate the strength and stiffness degradation at repeated lateral load reversals. The increment of the displacement amplitude was given as a fraction of the estimated beam yield displacement, Dy (14 mm); two different displacement rates were considered during the tests: 0.2 mm/s before the achievement of Dy and 1 mm/s after Dy."
More details regarding the loading history is also shown in the attached screenshot.

The number of cycles is enormous, it seems strange that the experimental setup had all these cycles. I reduced the number of step to 14410 yours were 144100 and I saved the data every 1441.
I suggest also to reduce to 3 partitions, 6 partitions for this model are too many.
