set-parameter commands don't work anymore!!!

[amnp95]

Hello.
I just tested the codes we used before and it was right but now all the setparameter commands give an error regarding to the "tag of parameters is already exist in the model". For example if you want to update the possion ratio for an ND Material like this:

op.setParameter('-val', 0.3, '-ele',1, 'poissonRatio', '1')
or
setParameter -value 0.3 -ele 1 poissonRatio

I don't know if somthing changed in the command with new commits or it is a bug.

Sorry, this was something I changed. @MassimoPetracca has a good work around until OpenSeesPy is updated.

Sorry to call you out @MassimoPetracca, but I think this is the same problem someone posted about in the OpenSees Facebook group and you had a good solution.

@amnp95 This was solved in PR #1078
As @mhscott said, until OpenSeesPy is updated, you can follow a workaround discussed here link

Basically, you can manually do what setParameter does behind the scenes:

replace
setParameter -value 0.3 -ele 1 poissonRatio

with a combination of
set dummy_param_id -12345; #just use a dummy Tag not used in any other parameter in your model
parameter $dummy_param_id
addToParameter $dummy_param_id element 1 poissonRatio
updateParameter $dummy_param_id 0.3
remove parameter $dummy_param_id

If you don't want to replace all your calls to setParameter, you can create a Tcl procedure (or a Python function) that shadows the original implementation until the next version will be released

Hello! I did not find setparameter and updateparameter in the source nDMaterial.cpp. Can you tell me how to implement updateParameter?
