hi,
i am trying to read case and data files. case file is around 100MB and data file is 200MB. While reading data file i get this error message.
Error: 1000000: Failed to allocate 59.53MB memory (..\..\src\amgif.c:884)

Error Objects: ()


My laptop has 3GB RAM and more than 50GB free in Hard disk. I am using windows vista: home premium.

What may be the reason.

thanks

I think the problem with the processor it self it can not handle big files (big mesh volume),since Fluent is a numerical solution method solver it needs a processor with higher capability

1.reduce the mesh size
2. I would try first with Pressure Based solver
3. parallel method or supercomputer

Thanks for the reply.
I am using Intel Core 2Duo T6400 processor in Dell Studio1435 laptop.
Thanks

Hello, I experienced a similar issue, except that I've been running the same job on the same computer, and I experienced this error after restarting in Windows. Restarting windows again and deselecting some of the transport equations didn't solve the problem. Changing the problem from double precision to single precision did the trick...this makes sense since memory requirements plumet.

Hi everyone

So I recently changed my solver method from pressure-based to density-based and even with 64 ram I am getting this failed to allocate memory error and have not been able to solve it in a week. Any idea on how to proceed? Thank you in advance.
