*COCA
Data format:
One line with 4 parameters, as follows:
IPRO ITYP CA CAL
Status :
Optional.
Restriction:
An element property must be previously defined
Purpose:
To define added mass coefficient for an element perpendicular to the axis of the element and in the axis direction. This is used when the relationship Ca=Cm-1 does not apply.
Details:
| Parameter | Description |
|---|---|
| IPRO | Identification number of a previously defined property with *CABPRO, *BEAMPRO, *RIGIPRO, *BARPRO |
| ITYP | Type of property. ITYP = 1: cable (*CABPRO) ITYP = 2: beam (*BEAMPRO, *RIGIPRO) ITYP = 3: bar (*BARPRO) |
| CA | Added mass coefficient perpendicular to element axis |
| CA_L | Added mass coefficient collinear to element axis |
