material deposition to substrate simulation at ABAQUS 1

[emrecan88]

Hi;

I am trying to simulate material deposition to substrate. In our case material is added to substrate and there is a distributed heat flux with constant velocity acting by node by node. I want to simulate showing the added material in the simulation and its effects. There is a command for that called Model Change in the ABAQUS. So is someone familiar to that kind of problem. And also I need to account mass diffusivity while the material is melting.

I will be gratefull for any advice you can spare

Best Thanks

Emrecan,
Yes, define the whole model first. In the first step, remove all the parts of the model that are not present from the start, and which you wish to add later:
*STEP
....
....
*MODEL CHANGE, REMOVE, ELSET=......

Then progressively add the elements in each subsequent step:
*STEP
....
....
*MODEL CHANGE, ADD, ELSET=ELSET1
...
*STEP
....
....
*MODEL CHANGE, ADD, ELSET=ELSET2

Thanks for your reply mrgoldthorpe but I want to model without removing just adding the elements. Is there a way to do this? And it is not CAE supported command so how can I get video of this simulation?

Thanks

1) ABAQUS requires that before you add (element sets) in a STEP you need to have defined them already. So do that.

2a) Not CAE supported command: so edit the .inp file.

2b) Despite 2a) you can still make a video after the analysis has run.
