abaqus fieldoutput by python

[Renny1988]

Hi to everyone and thanks for your help in advance.

I ran a simulation in Abaqus and i need to get the nodal forces and the nodal coordinates to use it for my weld model. My model has a large number of elements, and so for this purpose, i tried to use a python script, but i have encountered some problems.

To obtain what i'm looking for, i found that in abaqus documentations and i can write:

data1 = myOdb.steps['Step-1'].frames[6].fieldOutputs['fieldoutput1'].values[...].data


The problem is that i don't know what i must put in the brackets after 'values'.
If i put the number that identifies the node or the element, the data that return are uncorrect,
because they are different from the values i can see in the in the .odb file of my simulation.

If someone is able to help me please, i will very grateful.

Hi Lorenzo,

Values object is similar to python list. In square bracket you need to put digit.
The digit is not a node/element number as you expected. This is just address in the list.

The easiest way to control object content is to use print statement:

 print myOdb.steps['Step-1'].frames[6].fieldOutputs['fieldoutput1'].values[0]
print myOdb.steps['Step-1'].frames[6].fieldOutputs['fieldoutput1'].values[1]

Then you will see methods you can use with object like "data", "nodeLabel, "elementLabel" and many others.

So if you want check what element is under address 10 just use:

 print myOdb.steps['Step-1'].frames[6].fieldOutputs['fieldoutput1'].values[10].elementLabel

If the element id is what you are looking for then you can use:

 print myOdb.steps['Step-1'].frames[6].fieldOutputs['fieldoutput1'].values[10].data

to get the output values for element
