Thresholds and field functions
 

I have been having some trouble recently with a model that has a threshold that is monitoring a gas flow. I have set the scenes up in a single core mode, and added a scalar threshold with a field function of "mass density of gas" and it runs and solves fine and i can export each time step as an image to watch the gas flow.
I have then tried to run this over a few more cores but when i go to open the scene it goes into a updating scene loop that it never gets out of. I can create other things like iso surfaces, and can plot the filed function in sections, and can open a scene and a a threshold, but it does not seem to work as a threshold with a field function.

Any ideas people?

thanks heaps
