Hi David

Warning are often ok - MAPDL has dynamic memory allocation so the warning about in-core might have been just a warning before MAPDL allocated itself more memory.  Or it may have actually run out-of-core.  Check the output file.

See the MAPDL Help Operations Guide chapter 4.1 on the command line options.  There are two for memory that work hand-in-hand.  -m and -db

Don't try to allocation all the available memory to MAPDL if the model does not require it - the OS will use memory for things like caching files for I/O etc.
