Field |
Contents |
|
PID |
Unique identification number. (Integer > 0) |
|
MID |
Material identification number. (Integer > 0) |
|
OD |
Outside diameter of tube. (Real > 0.0) |
|
T |
Thickness of tube. (Real; T < ½ OD) |
|
NSM |
Nonstructural mass per unit length. (Real) |
|
OD2 |
Diameter of tube at second grid point – G2 on CTUBE entry. See comment 4. Default = OD (OD or blank) |
If T is zero, a solid circular rod is assumed.
PTUBE entries must all have unique property identification numbers.
For structural problems, PTUBE entries may only reference MAT1 material entries.
Tapered tubes are not allowed.
PTUBE data is converted to PROD data as it is read into OptiStruct. CTUBE data is converted to CROD data.
