I tried to perform an analysis with over 4 million tetrahedral elements. I got the error below. How can I solve this problem. I am using out-of-core, multiple threads and MUMPS solver.
Marc does not have a practical limitation on the number of nodes / dof. However, MAXNUM by default is set to 1000000 which represents the maximum number of nodes and elements.
This can be specified in the "include_win64.bat" file located in Marc installation ex: D:\MSC.Software\marc2021.2\tools
The message from .out file shows about 7.5GB is allowed, and Marc needs about 12GB of RAM.
Memory limit is specified in the same "include_win64.bat" file and by default set to max RAM available in the machine. If it is set to any value in your file, increase the limit, If not you should run on a machine with more RAM.
