Achieving specific surface shape

[SM1994]

Hello
I developing a model, in my model I want that the surface of my sample become similar to a desired shape by manipulating the inputs which are the pressure in each chamber, thickness and the chamber diameter.

Is there anyway that ABAQUS would manipulate/optimise the parameters so the surface area reach to a certain shape?
The pictures are attached.

Thanks

It should be possible with Python scripting or with Isight. But you will need a criterion that will let the software know that desired shape was achieved. For example you could place a rigid dome over the sample and enable contact. Then set the criterion to stop the analysis when contact between these parts occurs.

There are also other ways to get information about the thickness/position of a region.

- Request COORD to check the deformed coordinates of nodes
- Use a Cartesian connector between specific node pairs and request output of the connector displacement and connector position

Thank you for your responses.
Sorry for delayed reply as evidently my email notification was turned off.
However, in the meantime I had found a way to address that issue. My method is to generate a path using points (instead of nodes) then plot the XY and store the results, but since I want to change the intervals and some other properties, I want to feed my point list via a CSV file, instead of adding point list.
during the process of running the script I face the following error:
TypeError: expression;found 'file', expecting a recognized type filling string dict.

I understand the script does not recongnize the input file, but I do not know how should I modify it?
The CSV file is attached.

The error happens in line including:

[session.Path(name='point_list', type=POINT_LIST, expression=Data)]


Thanks for your help in advance.

Both Code and CSVfile is attached.
