3. Modeling A: axisymmetric thermal model#

3.1. Boundary conditions#

The segment AB is blocked in the Y direction.

The segment ED is uniformly deformed in the Y direction.

We consider a thermal transient applied to the inner skin (line AGFE).

The transient is a ramp from 150°C to 50°C in 10s. The transitory is divided into 6 moments.

The mesh size is in mm.

The mesh is a linear quadrangular mesh. It is converted to a quadratic mesh before mechanical resolution.

It has 190 knots.

The thermal stresses are extracted from the calculation results by the operator MACR_LIGN_COUP.

The constraint result of this calculation is printed for the FC segment by the operator IMPR_TABLE and by the operator IMPR_OAR.
