Topic: convergence criteria

Dear sir,

how can i identify the values of
1-displacement error tolerance
2-residual error tolerance
3-absolute residual error tolerance
4- energy error tolerance
and also the conditional break criteria for them (break immediately and break after step) in analysis of ultimate load or any other analysis ?

in ATENA-Troubleshooting section( 2.4.2.1 Recommended settings),there is default value 1% for the first three criteria (i.e., all except for the energy), and default value of Step Stop Multipliers to 10 (or 1000 for the energy).

Re: convergence criteria

Dear samuelhanna93, it is not clear from your question if you have already read ATENA Troubleshooting, 2.2.22 How to detect a structural collapse or ultimate load capacity? The latest version of the document is available from our web (Products - ATENA - Documentation).
