Fluids not rendering with arnold


hello guys,
I have a simple fluid sim in my scene, and when I render using arnold I get nothing, it only shows the geometry.
I tried caching then rendering, same thing. sometimes arnold renders a frame and most other time it doesn’t render. I even tried v-ray renderer and that didn’t work either. only maya software renders it.

if anyone can help I would really appreciate it.

I would upload the scene file but it won’t let me since I joined not too long ago.

thanks guys
