How to simulate compaction process of powder mettalurgy in Abaqus?

I am doing ph.d work related to powder mettalurgy 

I want to simulate the compaction process ( in powder mettalurgy) by using ABAQUS.It is very essential to find a way to create a model which will behave as such as PM part.

After modeling it is next work to find the proper analysis method to do analysis by applying compressive load to study the deformation of the PM Part. In ABAQUS, Modified Drucker-Prager cap model is widely used for the compaction problems of different metals in many research papers.

I have 2 problems.

1.How to simulate the compaction process?

2.For that simulation, how to create a Finite element model & a how to used drucker - prager model?

Can anybody help me
