I have a mdf file export from Adams Durability plugin . What am I supposed to fill in the Optional Keywords section to run SOL 112 ( modal stress recovery)?

Thank for any help

You cannot directly run the mdf file in Nastran. The mdf file is called inside the SOL 111/112 deck. Something like below.

ASSIGN INPUTT2='cantbeam.mdf' UNIT=31

SOL 111

and inside the begin bulk put

PARAM, ADMPOST, 2

The general procedure is outlined below.

1. Run SOL 103 with MNF.

2. Give MNF to Adams. Run the Adams code to generate the MDF file.

3. Give the MDF file to Nastran -- SOL 112 or SOL 111.

I am attaching a sample test files for you.
