Hello Guys,
I'm trying to calculate Material Data from input parameters and automatically create a model with the calculated data. In Python i've scripted the Model creation and tried it with fixed values. It worked fine. Now I'm trying to create lists in and insert it into the Abaqus command like this:
while T <= 453:
#CTE calculation
if T in [5, 77, 368, 453]:
if T <= 77:
CTE = (1/3 * T - 2/3)*10**-6
elif T <= 368:
CTE = (35/291 * T + 4580/291)*10**-6
else:
CTE = (18/17 * T - 5604/17)*10**-6
CTE_PEEK_Array.append((round(CTE,7), T))
...
mdb.models['Model-1'].materials['PEEK'].Expansion(temperatureDependency=ON,table=(CTE_PEEK_Array))
...
The linearly interpolated functions are correct, but The values in Abaqus are kind of random and not equivalent to the calculated data. Did somebody try the same approach? I tried to vary a lot of things, but it doesn't work at all. I think it has something to do with the float values and how abaqus reads these Values from the list.
As soon as this works, i would like to shift the funcions in dependency of other input Paramaters. If somebody has another idea on how to implement this kind of variation I would be very happy.
Kind Regards,
Waldemar
