Abstract Based on the moving-least-squares immersed boundary method, we proposed a new technique to improve
the calculation of the volume force representing the body boundary. For boundary with simple geometry,
we theoretically analyze the error between the desired volume force at boundary and the actual force
applied by the original method. The ratio between the two forces is very close to a constant and exhibits a
very narrow distribution. A spatially uniform coefficient is then introduced to correct the force and can be
fixed by the least-square method over all boundary markers. Such method is explicit and non-iterative, and
is easy… More >
