Clone a Study and Modify vs Clone a Load Case and Modify

[hbaileyA7A2P]

I am doing a static stress simulation with various load cases.  I was wondering what the pros and cons are of cloning the initial study and modifying the loads for the next load case vs cloning the load case and modifying for the next load case.  It seems that cloning the study preserves the results of each study, although it requires regenerating the mesh for each study.  Cloning the load case seems to preserve the mesh, but it seems to overwrite the results of the previously solved study.  Thank you for any help.

Hi @hbaileyA7A2P 

If I understand your description, you want to know if this setup:

• One study, two load cases

is better or worse than this setup:

• Two separate studies, one load case in each study.

In the end, both methods will provide the same result. Which method is better depends on these types of things:

• It is easier (faster) to switch between the results of two load cases in one study than it is to switch between two studies.
• How many times do you anticipate running the model? Are both load cases affected by any changes? For example, if you are making changes to the simulation model or constraints, that type of change will affect both load cases. It may be better to have one study with two load cases. (Less work to make the changes.) On the other hand, if load case 1 is "100% known" and you are rerunning the analysis because load case 2 needs to be changed to find "what load causes X", then it is faster to run load case 2 by itself in a separate study than it is to run both load cases everytime.

I hope this helps.

Hello @John_Holtz 

Thank you for your reply.  I am running the simulation 64 times as a base line and likely remeshing any cases that cause concern to further refine the results.  I have been using multiple studies with single load and constraint cases.  47 of 64 runs are complete.
