Thermal Shock Analysis of a Globe Valve


#1

Dear SimScalers,

in this week’s Project Spotlight we will have a look at the Thermal Shock analysis by @ahmedhussain18.

Type of analysis: Thermostructural Analysis - Uncoupled thermomechanical analysis (advanced)

Solver: Code_Aster

Transient or steady-state: Transient

Static or dynamic: Static

Nonlinear Analysis: True

Mesh Type: Tet-dominant

Number of cores used for the simulation: 32

Computation time: The analysis ran for a total simulation interval of 468 sec. (7.8 min.) on a 32 core machine and took around 323 min. to complete.
