I am trying to run a 3-D flow simulation over a wing. A couple days back, I ran the simulation with no problems. I have refined my mesh a bit and reduced the computational domain just to check grid independence of the results but no FLUENT kicks out every time I try to run my calculations. I have included a screen shot of the message I get. Any help would be greatly appreciated. Thank you

Since you mention that your simulation ran earlier with no issues, and now after refining the mesh it shows up this error, I think it would be because of the number of nodes in your mesh. Can you provide some numbers? No. of nodes (before refining and after refining), RAM specs?

[oyallou]

That would make sense. I believe before refining the mesh, the number of nodes were under 500k. Now, the number of nodes reaches nearly 2 million. 

 

The RAM on the computer is 3.49 GB available.

Quick question: How much is the total RAM in the computer?

[oyallou]

There is 4 GB of RAM installed.

oyallou, that would be a problem. I doubt if your computer will be able to handle those many nodes. I believe 1 to 1.2 million should work fine with 4gb RAM. But you've got to use another computer with more RAM or upgrade your RAM to handle more refined meshes (more than 1.5M nodes). Good luck !

I am running simulation based on electro-thermo-convection in a square cavity. The simulation give no error for low Rayleigh number (10000) and Electric Rayleigh Number (200). However, for a high Rayleigh number (50000) and at a constant Electric Rayleigh Number (200) an error occurred after series of simulation. Could anyone kindly provide any possible solution to this issue. The below is the screenshot of the problem am encountering. Thanks in anticipation.

Hello Oyallou, I have the same problem. Have you find the solution to this problem?

Thank You!
