Identifying Geometry and Details to Include in a Simulation - Lesson 1

Engineers use numerical simulations to analyze and evaluate their designs to make them better. However, before performing any simulation, it is important to choose the right geometry and level of details to include for analysis. The physics and objectives of the simulation help us to determine the level of geometry details needed for our analysis. It is a very important first step to have a right balance of computational efficiency and accuracy. This video discusses how to come up with the required geometric details.
