Adding material after execution of a step
Adding material after execution of a step
(OP)
I have a structure which is initially at Room temperature. Thermal load is applied until the temperature reaches steady state. At this steady state a film is deposited to the structure. Then it cools to room temperature.
Question: Does anyone know how to add material, i.e., a part instance) after completion of first step?

*MODEL CHANGE or *IMPORT ?

Thanks. But here is what I mean
Step 1: Part 1 is a metallic part, say 2-D axisymmetric model. Heat is applied until it reaches a steady state temperature in Step 1.
Step 2: Part 2 is added to one surface of the axisymmetric model and the same heat application is used to reach a steady state temperature. This is a stress free temperature of the assembly.
Step 3: Part 1 & 2 are cooled to RT by removing all loads in order to obtain the residual stress of film at room temperature.
These need to be done in one model in order for the process to work.
Thanks,

If I remember correctly import analysis has some restrictions. You should check the documentation for relevant information and examples on doing import analysis.

** Start with entire model

*INITIAL CONDITIONS, TYPE=TEMPERATURE
All, 20.0

*STEP
Step 1 Remove Part2 from entire model
*MODEL CHANGE, REMOVE

Step 2 Do thermal analysis for Part1, cooling to steady state
