CEL Abaqus 6.13 impact test Solid-Water-Sand

Hi to everyone ,


I am modelling an impact problem in Abaqus6.13. The problem is all about a jack-up leg impact on seabed. I have modeled a spudcan and tank setup according to the specification of a prototype which we created in our institute. According to the problem the  impact takes place under water and creates some normal force. I compared the software results and  experimental results. I came to observe a large impact force in the software results which is no way near to my experimental results. 


VUMAT Subroutines for multi-phase material behavior.

Hi everyone. I would like to know how to get started with a VUMAT subroutine for multiphases for example a subroutine for pore water and sand. It could be helpful when anyone could share VUMAT subroutines for learning such complex programmings. Could be appreciated when some one teaches with equations. thank you.
