Ok, Thanks.That's what I'm doing, but I wanted to have a rough number on what is the minimum number of elements you need in order to represent a certain frequency due to the wavelenght in, for example, steel.
Hi, I'm working on a project that entails calculating the frequency response on a steel structure made with 2D elements.
Does anybody knows a rule of thumb to define the minimum size of elements in order to be able to obtain reasonable results for a certain frequency?
Say for example that I...
