OptiStruct is not using the second RAM
Even though my laptop has 2 RAMs of 8GB; I'm facing with an error as ''*** ERROR # 3401 ***
System does not have enough memory available for MUMPS solver. MUMPS needs
addtional 448 MB. Please use a computer with bigger physical RAM.'' for a non-lineer static analysis that requires just 10.497GB ram capacity. How can it run with both 2 of my rams?

The solver has available at the beggining of your run, around 10GB of RAM.
But according to the .out file, your model requires at least 26GB RAM in the worst case scenario (out-of-core).
So your system is not enough for running this model.
You may want to try a larger machine or reduce your model.
Is it a 2nd order model?
Got it sir, appreciate for answer. Its my shame to ask before anayzing the out file carefully. Sorry for this beginner mistake.
Nope, just a helical gear pair model from hex8s which includes only 5 teeth of both but the mesh size is 1mm and a few contacts exist. Seems like it will be a nice lesson to get a mesh convergence know-how then:)
