v4.25.001 TTLV01 — Sphere: convective heat exchange

Summary:

This test is the result of the independent validation of version 3 in linear transient thermal.

It is a three-dimensional problem represented by four models, one solid, the other three axisymmetric.

The features tested are as follows:

• volume thermal elements,

• axisymmetric thermal elements,

• transient thermal algorithm,

• boundary conditions: convection.

The results are compared with those provided by VPCS.
