hello, everyone. I want to know how to run a series of cases with the same model, the only difference is boundary conditions. say a mass flow rate changing from 1kg,2kg,3kg……10kg. I don't want to set the boundary conditions one by one. Is there a way to realize it? can you give me an example file with the correct format? thanks!!!

Generate a CCL file. Then generate copies of the CCL file with the boundary condition modified to have 1kg/s, 2kg/s etc. Then do a batch script to run them all, something like

cfx5solve -ccl run1.ccl
cfx5solve -ccl run2.ccl

Alternately you can do this with parametric modelling in workbench.

Opaque will become famous soon enough
There are many ways to answer this question. Here are some (skipping CEL to minimize them)

1 - Glenn's suggestion: generate one command file per value of the BC, and use the command line repeatedly

2 - Create a script in any language (Perl, csh/bash/ksh, Python) that will do:
Extract the command file (using cfx5cmds -def ...)
Loop over the values of interest
Search for value to be replaced
Replace such value
Submit simulation using cfx5solve -def .. -ccl new_file.ccl

3 - Use the latest version of the software, and use the new feature for this intended purpose (Operating Maps). Read the documentation, and you will be on your way, i.e. interpreting results.

Hope the above helps,
