PARAM, EHD
Bulk Data Entry Prints the inverse of the stiffness matrix created by static reduction to Fortran unit 3.
Parameter | Values | Description |
---|---|---|
EHD | <YES,
NO> Default = NO |
This parameter is used to
print the inverse of the stiffness matrix created by static
reduction to Fortran unit 3. The inverse
reduced stiffness matrix is written in NASTRAN MATPRN format. To perform static reduction there must be ASET data and PARAM,EXTOUT,DMIGPCH in the input data. After the stiffness matrix is reduced to the ASET DOF, its inverse is calculated and written using NASTRAN MATPRN format to Fortran unit 3. PARAM,EXTOUT,DMIGPCH must also be specified when this parameter is used in order to trigger the static reduction. |
