Subject: [Ironpython-users] Scripting Ansys with IronPython - Unable to callvalues from dictionary<BR>
<BR>
Hi all!<BR>
<BR>
I have a problem with scripting the FEA software Ansys Workbench with<BR>
IronPython. I need to come up with a script that gets the variable<BR>
values in an optimum point that I have found using the optimization tools.<BR>
<BR>
I found some help for this with "VerifyCandidate" in the scripting guide<BR>
in the Ansys manual and did this in the Ansys Workbench command window:<BR>
<BR>
IronPython 2.6.10920.0 on .NET 2.0.50727.3625<BR>
system1 = GetSystem(Name="GDO")<BR>
optimization1 = system1.GetContainer(ComponentName="Optimization")<BR>
optimizationModel1 = optimization1.GetModel()<BR>
verifiedValues = optimizationModel1.VerifyCandidate(Index=0)<BR>
print verifiedValues<BR>
{'/Optimization/OutputParameter:P3': '-0.035979796200990677 [mm]',<BR>
'/Optimization/InputParameter:P1': '5.5 [mm]',<BR>
'/Optimization/OutputParameter:P2': '0.07417053282883164 [kg]'}<BR>
<BR>
Now I have a dictionary with my one design variable P1 and two responses<BR>
P2 and P3 with their values at the optimum. Looking good so far. So now<BR>
I only need to get my hands on the values and I'm home free.<BR>
<BR>
I think this should give me the value of the design variable P1:<BR>
<BR>
verifiedValues['/Optimization/InputParameter:P1']<BR>
KeyNotFoundException: /Optimization/InputParameter:P1<BR>
<BR>
But no, I get an error saying that there is no such key. But when I list<BR>
the keys, it's right there:<BR>
<BR>
dict.keys(verifiedValues)<BR>
['/Optimization/OutputParameter:P3',<BR>
'/Optimization/OutputParameter:P2', '/Optimization/InputParameter:P1']<BR>
<BR>
So this is my problem. I've tried calling it without the quotes or with<BR>
double quotes and any other variation that I've come up with. If I make<BR>
a new dictionary manually with the exact same keys and values copied<BR>
from the screen it works just fine. But I can't get anything out of the<BR>
original dictionary.<BR>
<BR>
Any ideas on how to get it working or what could be done to debug this?<BR>
The only idea I've had is that for some reason the keys are printed<BR>
incorrectly and some characters are actually missing from their names,<BR>
but I might be totally off with this.<BR>
<BR>
Needless to say that I'm a total newbie with Python. Probably the right<BR>
people to ask are other Ansys users, but I've had no luck finding one<BR>
that could help me. Maybe my luck will chance with you Python gurus :)<BR>
<BR>
All help is greatly appreciated!<BR>
<BR>
Best regards<BR>
