GENMATRIXDAMP,<begin>,[end],[stride],<damp>

ACS-SASSI can convert the MATRIX27 element connections and the ANSYS(R) mass matrix directly from the *.cdb. However, SASSI uses a complex stiffness that can't be converted directly from the data in ANSYS .cdb file. The GENMATRIXDAMP will take the stiffness matrix definition in ANSYS(R) and a user defined damping value to convert the stiffness matrix from ANSYS into a complex stiffness matrix that SASSI can use.

• begin - the first matrix property to be converted
• end - last matrix property to be converted. When using default (or left blank) the end value will be set equal to the begin value. (default = -1)
• stride - increment for the next matrix property to be converted (default = 1)
• damp - user defined damping value
