Quality metrics for meshing refer to the criteria used to evaluate the accuracy and efficiency of mesh generation in computational simulations.

• Aspect ratio: measures the quality of elements based on their shape

• Skewness: evaluates the distortion of elements

• Orthogonality: assesses the angle between adjacent elements

• Convergence: determines the mesh resolution needed for accurate results

Y+ value is a parameter used in computational fluid dynamics to determine the accuracy of the simulation near solid boundaries.

• Y+ value is a dimensionless parameter that represents the ratio of the distance from a solid boundary to the first grid point to the viscous sublayer thickness.

• It is used to ensure that the simulation accurately captures the boundary layer flow near solid surfaces.

• A Y+ value of around 1 is typi...read more

Bending moment is the force that causes a beam to bend. Torque is the force that causes an object to rotate. Beams can be classified into different types based on their shape and support. Angle of projection is the angle at which an object is projected. Composite materials are made up of two or more materials with different properties.

• Bending moment is the product of force and distance from the force to the point of ro...read more
