"Reduce computational domain Coarsen mesh/grid in areas that don't need refinement Use internal flow" Done. "potentially upgrade hardware." Sadly I'm too poor for that at the moment. Thanks for all the help!

Thats a beefy processor.

I have an i7 M640. It's a dual core but task manager shows 4 cores. Flow Simulation only uses 2.

Flow Simulation is using 2 cores. I believe the Intel Core i7 is effectively a dual-core processor even if it only has one core. That's my non-expert take on it. The wind tunnel is working better. The min/max table is not showing me unrealistically high mach numbers or low temperatures...

Here is where I'm at: I did coarsen the grid and customize the computational domain more. I got a simulation time of about 20 minutes on my 2.8GHz Intel Core i7 laptop with 8gigs of ram. Due to time constraints on this endeavor it will have to do. Now that I know that a 24-hour simulation is...

The flat plate does have an inlet on one side, yes. Now that you bring it up I might remake it into a long cylinder anyway.

I'm not sure I understand your question. Are you asking if there is a reason I modeled the engine as a plate instead of a cylinder? The reason is that I am concerned more with heat flow in the plate than a perfectly simulated flow field. Do you think I should change it?

Should I use the "high mach number" option since the exhaust is traveling at mach 0.91? I think the flat plate does disrupt the air in unrealistic ways but I don't think it will be a problem for this simulation. My goal is to compare different materials in the plate, such as Aluminum and...

Oops here is the file.http://files.engineering.com/getfile.aspx?folder=fbbeb0cf-74fe-4819-ad0b-28a798073256&file=model.zip

Here are three pictures of my model. The large rectangular box represents the pylon of a jet. The small square in the bottom right of that is a 1-in thick plate made of several layers. I made an indent in the pylon to allow the plate to fit flush with the surface of the pylon. The disk...

I am modeling air flow from the atmosphere and from jet exhaust over a plate on the side of an airplane. Solidworks Flow Simulation works fine for air but when I check the "heat conduction in solids" option under General Settings the simulation time shoots up to a ridiculous amount of time...
