Unformatted text preview: General Analysis Procedure Chapter 5 February 7, 2006 Inventory #002268 5-2 INTRODUCTION TO ANSYS INTRODUCTION TO ANSYS INTRODUCTION TO ANSYS - Part 1 Part 1 Part 1 Training Manual Chapter 5 - General Analysis Procedure Overview • The objective of this chapter is outline a general analysis procedure to be used to solve a simulation. Regardless of the physics of the problem, the same general procedure can be followed. • The problem on the following slide will be used to demonstrate the general analysis procedure. February 7, 2006 Inventory #002268 5-3 INTRODUCTION TO ANSYS INTRODUCTION TO ANSYS INTRODUCTION TO ANSYS - Part 1 Part 1 Part 1 Training Manual Given: A 1” thick spherical aluminum tank with a height of 180” and radius of 100” tank is filled with water to a height of 80”. The aluminum properties are E = 10E6 Psi, ν = 0.3. Question: Predict the membrane stress distributions in the meridional ( σ m ) and circumferential ( σ c ) directions? 1 “ 80 “ 100 “ 100 “ 3 163279 . 1 in lbf = ρ m σ c σ Stress Convention A A Section Definition Section A-A Chapter 5 - General Analysis Procedure …Overview February 7, 2006 Inventory #002268 5-4 INTRODUCTION TO ANSYS INTRODUCTION TO ANSYS INTRODUCTION TO ANSYS - Part 1 Part 1 Part 1 Training Manual Every analysis involves four main steps: • Preliminary Decisions – Which analysis type? – What to model? – Which element type? • Preprocessing – Define Material – Create or import the model geometry – Mesh the geometry • Solution – Apply loads – Solve • Postprocessing – Review results – Check the validity of the solution Preprocessing Solution Postprocessing Preliminary Decisions Chapter 5 - General Analysis Procedure …Overview February 7, 2006 Inventory #002268 5-5 INTRODUCTION TO ANSYS INTRODUCTION TO ANSYS INTRODUCTION TO ANSYS - Part 1 Part 1 Part 1 Training Manual Chapter 5 - A. Preliminary Decisions Which analysis type? • The analysis type usually belongs to one of the following disciplines: Structural Motion of solid bodies, pressure on solid bodies, or contact of solid bodies Thermal Applied heat, high temperatures, or changes in temperature Electromagnetic Devices subjected to electric currents (AC or DC), electromagnetic waves, and voltage or charge excitation Fluid Motion of gases/fluids, or contained gases/fluids Coupled-Field Combinations of any of the above • The appropriate analysis type for this model is a structural analysis!...
