Dear sir, 

Does that mean i can if i assume as a continuum, i just need the data of sand, soil, or gravel separately, then i can have the ansys system simulate the combination for me?

If so, how should i go about doing so? what part of ansys should i use? Ansys fluent?

may i know ho i should go about looking for information onhow to assume it as a continuum, since i would like the sand mixture to act as a road to test the friction coefficient with a simple tire. 

Thank you for your help.
