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.
