Question

A finite element mesh is refined by subdividing existing elements into two or more elements of the same type, what is the name of such a refinement?

(a) h-version mesh refinement

(b) p-version mesh refinement

(c) h, p-version mesh refinement

(d) p, h-version mesh refinement

This question was posed to me in unit test.

My question is taken from Modelling Considerations in portion Interpolation Functions, Numerical Integration and Modelling Considerations of Finite Element Method

Answer 1

The correct option is (a) h-version mesh refinement

For explanation I would say: Refining a mesh by subdividing its existing elements into two or more elements of the same type is called the h-version mesh refinement. Alternatively, in p-version mesh refinement, the existing elements can be replaced by elements of a higher order. The h, p-version mesh refinement, in which the elements are subdivided into two or more elements in some places and replaced with higher-order elements in other places.
