Abstract (EN): Cardiovascular diseases are one of the leading causes of death in the world, with about 15 million deaths per year. Therefore, it is important to develop strategies to allow the study of this type of diseases, in order to understand how to oppose these numbers. To this end, biomechanical simulation using discrete numerical techniques, such as Finite Element Method (FEM) and Radial Point Interpolation Method (RPIM), emerge as unique techniques to study haemodynamics. The aim of the present work is to compare the velocity profile of a discretized model of a tubular straight artery, using two methods, FEM and RPIM, in order to compare the results obtained with each one. FEMAS software was used and allowed to conclude that RPIM is preferable to FEM since, the first, presents a more uniform velocity profile of the blood flow when compared to the results obtained with FEM, being more suitable for this type of analysis. However, the RPIM parameters need to be calibrated since the clot presented a larger size than what should be expected when using this model.
