![]() ![]() You log the time at which a car passes by you at some street corner, let’s say A. You want to understand the motion of the automobiles passing by, you can do that in various ways but you decide to do it the following way. Now you are standing on a street in Basel and observing the cars passing by. Euler and also assume for our convenience that cars have been invented already (almost a hundred years before they were, originally). ![]() Let’s assume for a second that you are Mr. The interaction behavior between the two is modelled by Contact definition. The CEL method enables the user to selectively mesh the analysis components accordingly-the components/bodies undergoing large deformations can be meshed using Eulerian technique while the remaining using the conventional Lagrangian technique. In such cases Eulerian meshing approach is more suitable. The most common mesh approach used in finite elements is the Lagrangian approach (discussed later), this approach is not suitable for cases where excessive element distortion is expected. The purpose of this technique is to avoid mesh problems when performing simulations that involve high/extreme deformations. This analysis techniques combines two mesh approaches-Lagrangian and Eulerian-in the same analysis. ![]()
