It should be a routine bug-finding exercise to fix this. * Have you checked the air is escaping out the ends as it should? * If you are modelling this in 2D have you put symmetry planes front and...

I would probably put the top, bottom and edges all as separate domains for a total of three domains. But you could use sub domains if you like. But sounds like you can model it in 2D with a simple...

Does the plastic go beyond the plate edge? Or does the fluid is displaces (air?) have a significant effect on things? Assuming that you need...

You should go back to hex meshes and fix the folding mesh problem. Also, if you expect the flow to be 2D axisymmetric you should...

Does the flow have 2 symmetry planes or is it actually a 2D axisymmetric flow? If it is 2D you will save heaps of time by running it 2D. Also your mesh is...
