My model takes a long time to analyze. What can I do ?

 

Size of the model and number of load cases directly affect the analysis time. So leaving out any detail that is not important for the analysis is something worth considering. For example there may be stairs, handrails, access ladders, monorails, connection components like gusset plates, stiffeners and such other entities that may be left out from an analysis model. Also there may be certain loads/combinations that you may already know will not be governing the analysis/design. Avoid including these in your model, specially if analysis time is a concern. Using a relatively coarser mesh, changing some of the primary loads to reference loads, changing REPEAT LOADs (if any) to LOAD COMBINATIONs (if the analysis is linear one), are some of the other things to try out. Also make sure that you are using the latest STAAD.Pro CONNECT Edition (ver 22.05.00.131 and up ) as that has the faster solver available for all license types (Advanced and Basic). Also last but not the least, if you are trying to run the analysis for a file which is on a network drive, try copying the file to your local machine and see if the analysis time improves. Software performance can be affected significantly by network speed/activities.
