RSA - Time consuming Calculation issue

[L]

Hi,

We're currently working on a model which is way much to slow to calculate, it takes hours to run a calculation.

There are about 2000 nodes and 3000 elements, each of them have specific loads under and various releases.

Each time we run a calculation, it first suppress the previus model, then take for ever to consolidate the model.

The several iteration using the Newton-Raphson method are really slow so we wonder which would be the best

settings to perform the calculations.

Thanks,

Guillaume

Each time we run a calculation, it first suppress the previus model, then take for ever to consolidate the model.

Use from time to time "save as" and save file as rtd without results under new file name to compact file.

So your file can be 11 MB instead of 950 MB

Consolidation takes less than minute.

You do not have to calculate simple cases, set them as auxiliary cases.
Some combinations are slower convergent some faster.
comb 231 232 (each) - 90 seconds to converge (multithreaded solver)
so you can expect \ estimate calculation time 3-4h minimum
