You can set it to any positive integer value equal to or less than 14000000, representing 56 MB of open core. Setting it to any value outside of that set (e.g. "14000001", "-5", "2.71828", "donuts"), regardless of file validity or model scale, will cause a fatal message to be issued.

The program set the largest number at 14000000, you ask more than that, sure you will get a warring.

You need to raise that largest number in the program.

You are right; it needs recompiling as explained in NASINFO file:

"AN IN-MEMORY DATA BASE IS AVAILABLE FOR ALL PLATFORMS.  THE IN-MEMORY
DATA BASE ELIMINATES I/O TO DISK.  LOGIC EXISTS TO AUTOMATICALLY WRITE
FILES TO DISK AFTER THE IN-MEMORY DATA BASE SPACE IS EXHAUSTED.  THE COMMON
/ZZZZZZ/ IS USED FOR ALLOCATING OPEN CORE AND SPACE FOR THE IN-MEMORY
DATA BASE.  THE SIZE OF COMMON /ZZZZZZ/ IS DEFINED IN ./MDS/NASTRN.F
(SEE ARRAY "IZ" AND VARIABLE "LENOPC"). "

"USERS ARE ENCOURAGED TO RECOMPILE "NASTRN.F" WITH A LARGER ALLOCATION
FOR COMMON /ZZZZZZ/ IF THEIR PLATFORM SUPPORTS A LARGER MEMORY ALLOCATION. 
A LARGER ALLOCATION OF COMMON /ZZZZZZ/ PROVIDES FOR MORE SPACE FOR THE
IN-MEMORY DATA BASE AND ALLOWS FOR MORE FILES TO BE MAINTAINED WITHIN
THE IN-MEMORY DATA BASE.  USERS SHOULD ALWAYS ALLOCATE SUFFICIENT
OPEN CORE TO PREVENT SPILL LOGIC (E.G., SEE USER INFORMATION MESSAGE
3023)."

In fact it is compiled to a maximum of 400000000 not 140000000 as you can easily check changing OCMEM environment variable to any value bigger than it (Ubuntu version).

and CTRIA3 is available, check latest User Manual file (in TXT file format, the PDF are outdated):

"CTRIA3 - Triangular Element Connection

Description

Defines a triangular plate element (CTRIA3) of the structural model. This is
an isoparametric membrane-bending element, with variable element thickness,
layered composite material, and thermal analysis capabilities.

Format and Example"
