[Cooper24]

I am modelling laser melting in FLUENT. After my simulation I am trying to visualise it in CFD-Post. My results are not visible upto the mark. In the figure below(a), there are metal particles above a solid metal base. The metal particles are patched with volume fraction. I have used isosurface and volume rendering for metal phase (it is a multiphase flow with two phase-air and metal) to visualise in CFD-Post. But the results don't look very promising. There is some issue with the visulization.
The second image(b) is from a published paper and they have also used CFD-Post but their results look very good. Can someone please help where I might be committing mistake? Any help is much appreciated. Thanks in advance.


P.S: As I understand, my spherical particles are not able to fill completely with material during volume rendering.
