Card 9 - PROTECTIVE_LAYER Protective Layer Definition

This optional card defines a boundary condition that adds a thermal barrier coating, protective layers, on top of thermal elements for heat transfer modeling.

Parameters: KODE, N1, T1, T2

KODE

KODE is the code PROTECTIVE_LAYER (or 123)

N1

N1 is the PROTECTIVE_LAYER card ID. Cards with the same ID reference the same Protective Layer.

T1 = NAME

T1 = NAME (or 1) specifies the Protective Layer simulation object name in T2.

T1 = SELECTION

T1 = SELECTION (or 2) specifies a selection of thermal elements on which the Protective Layer simulation object is applied. The selection is represented by the group name T2.

T1 = MATERIAL

T1 = MATERIAL (or 3) specifies the material ID in T2.

T1 = THICKNESS

T1 = THICKNESS (or 4) specifies the layer thickness value in T2.

  • If the thickness is constant, then its value is specified in T2.
  • If the thickness is table dependent, then T2 is a table multiplier and T3 has the form Tn, for example T39, where n is a table number referencing the TABTYPE and FIELDTYPE cards.

T1 = SUBLAYERS

T1 = SUBLAYERS (or 6) specifies the number of sublayers per layer in T2. For more information, see Protective layer in finite element method.

T1 = OPTICAL

T1 = OPTICAL (or 5) specifies the ID of optical properties of the referenced OPTICAL card in T2.
