Immersed boundary (red) representation in polynomial space with 16 terms. Comparison of the numerical (black) and the analytical integration (blue) for the masking function \(\chi \). Black dots represent the non-equidistant integration points (Chebyshev nodes). a Wall location between two Chebyshev nodes and b wall location exactly at a Chebyshev node
