Jan Stránský proposed the following answer:
Hello,
> calculate RMSE with exp values
the key here is to define exp values "well" - which values (peak values?
curve shape? some overall trend, like line slope? ...?), how to measure
them (not to take "errors" (some peak force due to oscilation), but not
missing relevant trends), set proper relation/weights between the values
.....
Dimensional analysis can help (search "dimensional analysis
calibration") reducing the number of values.
> how can run the simulation (calibration process) continuously, without
pressing run
use O.run [1], possibly with O.wait [2], waitIfBatch [3], have a look at
manual [4]
For "multiple running", you have several options:
- yade batch mode [5], "manual" trial-and-error optimization of parameters
- create a (python?) program running simulations, evaluate results, updating
input parameters ...
- ... (many more options)
Cheers
Jan
