I want a highly structured hexahedral mesh. The PEMFC consists of an MEA which is essentially 5 very thin rectangular prisims stacked on top of each other, and bi-polar plates and gas channels on the top and bottom. These channels imprint onto the surface of the MEA when I share the topology for the entire domain (which is recommended by the handbook). The middle 3 layers I can mesh using a sweep method, but the outer 2 layers cannot use the sweep method due to the gas channel imprint on the top surface (pic 1. Bi-polar plates and channels hidden).<\/p>\n<p>My current solution is to split the outer layers of the MEA into 2 segments. The inner can be meshed using the sweep method and the outer I just tell to mesh with hex dominant method. This works for almost the entire domain except the corners (pic 2) which make these random pyramid and wedge elements. I have tested this in fluent and it works alright, but I would prefer to have a fully structured mesh.<\/p>\n<p>Does anyone know how I can stop workbench from making these ugly elements in the corners of the MEA? Preferably in workbench, but if you think I need to change software to a different mesh package, let me know.
