is there any way to make external super element defitinin for cavity (PSOLID) elements so that include K , M as *.asm and *.pch file during sol 111 solution ?

You are looking to generate and external superelement that represents only the internal acoustic cavity, right? First, lets look at how the acoustic cavity and structure communicate. The coupling matrix, called the A matrix, connects the external surface of the cavity to the 'touched' surface of the structure. So as an external superelement, the cavity would need to have all of the external surface grids in the ASET. That is not really efficient with respect to matrix size or processing.
What leads you to wanting the acoustic cavity to be a standalone external superelement?
