floxpress flow paths broken

Hi guys,

I'm trying to use floxpress to get a general idea of how water flows through one of our products. The product has perforated sheet baffles in it designed to reduce the velocity inside the vessel. I've modelled it and the simulation seems to run fine but the results are as shown in the attached image, just bits and pieces everywhere no full flow paths.

Any ideas?

thanks in advance.
