Dear all,

I am trying to simulate the alkali-aggregate reaction that results in a strain of the concrete mass.

First i performed a transient thermal analysis to determine the temperature of each node in each time step.

Then, using the temperature values in each node (in each time step) I calculated the correpondante strain values (using a python script). 

Now i would like to apply those strains to the nodes in my FE model, for each node i would like to apply a strain value, for each time step.

I have read about the INISTATE command (successfully applied a constant strain value to the geometry) and i would like to ask if this would be a possible solution to my problem and how would it be implemented.

Thank you all.

Hi,

Please see if the following link helps: INISTATE Command (ansys.com)

Hi,

 

Thank you for your comment, it helped.

However i am still far away from solving my issue, is it possible to apply a different strain for each node in each load step? I have 5000 nodes and 960 loadsteps...

Hi,

You can use nested do loops to select loadsteps and nodes per loadstep.
