Hello everyone, I encountered an error when ICEM outputs the .msh file, specifically when the file size reaches 4.19GB while it's still in the writing process. The same error always occur at 4.19GB, regardless of the of the mesh size. I've successfully output file sizes smaller than that.

The error just says "error writing to file", without further description of the error (see attached image). I'm not sure if this error has to do with memory limitation in ANSYS.

I'm running the ICEM software on a school virtual desktop (28GB RAM) and writing the file to my personal laptop via Citrix Receiver.

Any ideas or suggestions?

Thanks all

Choose common solver ANSYS
and solver as ANSYS FLUENT instead of FLUENT V6
