Problem in acoustic modes analysis
Problem in acoustic modes analysis
(OP)
Hello to everyone,
I am having problems with a eigenvalues analysis. In particular I need to extract the acoustic modes from my model.
I have created a fluid material (mat10), specifying all the properties needed, but when I run the analysis the following fatal error appears:
*** USER FATAL MESSAGE 2113 (EMG)
ELEMENT 1 REFERENCED MATID 1 WHICH CANNOT BE USED TO OBTAIN REQUIRED PROPERTIES.
User information:
A search procedure in MAT allows any possible MATi entry to be
referenced under any INFLAG. However, only certain material formats
can be used to construct the required output in /MATOUT/.
Make certain the element can reference the material entry type.
And that's for 100 element. Could anyone help me with this issue? Which material should I create?

RE: Problem in acoustic modes analysis
The issue lay in the PSOLID property format which did not respect what is written in the NX Nastran QRG at page 2220 (Bulk data entries -PSOLID).
