A new algorithm of the Lagrangian vortex method for incompressible flow simulation is considered. The boundary condition on the surface of the body is satisfied by introducing a vortex sheet, the intensity of which is determined from the equality condition between tangent components of the limit value of the flow velocity and the velocity of the body surface. To solve the resulting boundary integral equation, the T-scheme and the potential reconstruction algorithm based on the least squares method are used. The results of applying the algorithm to the computation of the components of the added mass tensors are presented.
