Difference between node & element & block

Click For Summary
In analysis software like Ansys, a node is a specific point where field variables are calculated, while an element refers to the finite element itself, which is a smaller unit of the overall model. Blocks are often used to describe larger sections or groups of elements that share similar properties or behaviors. Understanding these distinctions is crucial for effective finite element analysis (FEA), as they impact how models are constructed and analyzed. The terms are well-documented in various resources, including FEA theory literature. Clarity on these definitions enhances the accuracy of simulations and analyses in engineering applications.

FEA Theory: Model [a] body by dividing it into an equivalent system of many smaller bodies or units (finite elements) interconnected at points common to two or more elements (nodes or nodal points) and/or boundary lines and/or surfaces.

A node is a specific point in the finite element at which the value of the field variable is to be explicitly calculated.

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
