CAESAR II Statics and CAESAR II Dynamics training. /// CAESAR II Statics teaches basic CAESAR II operation, model creation and output review with a focus on evaluating piping systems under static loading conditions (e.g., thermal strain, deadweight and other applied loads). Additionally, this course incorporates Piping Code background along with proper engineering application of the software. Attendees develop real world knowledge of static analysis while also learning how to use CAESAR II for cost effective piping design. /// CAESAR II Dynamics is highly regarded for its blend of background theory, use of CAESAR II and engineering application. Attendees develop real world knowledge of dynamic analysis of systems while also learning how to use CAESAR II for cost effective piping design.
