Fused deposition modelling , part simulation for residual stress

Dear all,

I am working on residual stress analysis of additively manufactured thermoplastic composite parts. I am using extrusion based additive manufacturing called screw extrusion additive manufacturing. In order to simulate residual stress i have to develop a path for heat and material input in Ansys. I have create code for that. Can please let me starting points or give a guidance to perform such a simulation.

I have intial idea that i have to use element death and birth. How can i devlope a element death and birth command for complex geometries.

Thank you in advance.
