Definitions

Field Contents SI Unit Example
PID Unique property identification number.

(Integer > 0)
MID Material identification number.

(Integer > 0)
OD Outside diameter of tube.

(Real > 0.0)
T Thickness of tube.
= 0
A solid circular rod is assumed.

(Real; T ≤ ½ OD)
NSM Nonstructural mass per unit length.

(Real)
OD2 Diameter of tube at second grid point - G2 on CTUBE entry. 2

Default = OD (OD or blank)

Comments

  1. For structural problems, PTUBE entries may only reference MAT1 material entries.
  2. Tapered tubes are not allowed.
  3. PTUBE data is converted to PROD data as it is read. CTUBE data is converted to CROD data.
  4. This card is represented as a property in HyperMesh.
