A new tetrahedral finite element is proposed, which allows h-refinement to proceed simply, without the need to pay attention to the geometric quality of the elements. The new element is used to find the capacitance of various three dimensional structures h-adaptively. For one example, the h-adaptive mesh contains six times fewer degrees of freedom of a uniformly-refined mesh of equivalent accuracy
