Catia Static Analysis Reduce Calculation Time?

[MBCatia]

Hello everbody,

I am making static analysis with catia
When calculate resoults so long time spend. For example 3 hours I am waiting then I try another one again 2-3 hours taking time. This is tiring.

Is there any idea that I can take more quick calculate static analyis when I make analyis.

Thank you.
Best regards

What have you tried?

For what kind of part do you need stress analysis?
What kind of mesh do you use?
Is mesh size the same thru all model?
Try to make a smaller mesh only where you expect to have critical values of the stress/

1500 x 3000 x 1000 mm³ part with thin

There are resoults attached.

Parabolic mesh I used. I used critical please local/size meshes.

Resoults are every time changing with mesh size how can I think which one is the best mesh size? Global error rate %8 one best one? But with small mesh calculatinon time is so long time.

Comment please

Best regards.

Smaller mash precise results you will have.
Try to create smaller mash only in the areas where you expect to have critical loads, and bigger mash in areas where that is not important

Thank you,

I have one more question please.

I made this table with welds and I made analysis just like a part.

How I must think weld effects in fact this table is not just like a casting part I used weld for unite parts.

How I must thisk weld effect?

I hope I explain well.

Thank you for your interest.

Best regards.
