👉 Mudhole, also known as a pressure vessel or a hydraulic cylinder, is a type of rigid container used in fluid mechanics and structural analysis to simulate the internal behavior of fluids. It is commonly used in the design of hydraulic systems, where it can be used to model the flow patterns of fluids in pipes, tanks, or other structures. The term "mudhole" comes from its resemblance to mud, which is a solid material commonly found in soil and rock formations.
