PAT312 - Thermal Analysis Using Patran Thermal

Horizontal spacer

Day 1 is an intensive review of Patran focusing on building heat transfer models for Thermal. Days 2 through 4 begin with an initial overview of Thermal capabilities followed by exposure to all features of Thermal accessed through Patran. Each lecture and lessons will instruct you how to setup, execute, and post process the results of a heat transfer analysis. Lessons increase in the level of detail and complexity through the week.

Length: 
5 days
