Mesh not conforming to particles?

[3mbic]

I am new to realflow and am having trouble at the meshing stage of my project.

The particle simulation looks perfect and is the correct shape however the mesh, when built, does not follow the shape the same way. To the point that it breaks up entirely at one section. I have attached some images to show what I mean (sorry but for NDA reason's I can't show the entire mesh of the object it is flowing through).

I watched a few tutorials and paged through the forum but even after some tweaks I just can't seem to get it to look right. Any advice? Thanks a lot!
