Adaptive Semi-Structured Mesh Refinement Techniques for the Finite Element Method

The adaptive mesh techniques applied to the Finite Element Method have continuously been an active research line. However, these are usually tetrahedra. Here, we use triangular prismatic element as discretization shape for a code with adaptivity. process consists of three steps: error estimation, marking, and refinement. We adapt already other shapes prisms, showing differences here in detail. five different marking strategies, comparing results obtained parameters. strategies conformation necessary avoid hanging nodes resulting mesh. also two special rules ensure quality refined show effect Manufactured Solutions numerical validate implementation introduced.
