  1. Hi,I am trying to simulate a bird impact on a plate with RADIOSS. So I am creating my model on hypermesh now, i chose to consider the bird as a fluid with a density of 438 kg/m3. I would like to work with SI units and the dimensions of the bird are : 0.1325m long cylinder with two hemisphere ends having a radius of 0.075m. I am now trying to mesh this geometry with the SPH module in hypermesh. So i entered a pitch of 1e-3m and a density of 438kg/m3 as i said before. But when i create the mesh, nothing happen and i only get this message "0 mass elements created". I attached my file with the topic. I don't know what could be my error, more of that I tried to do it using mm instead of m and it worked... But I really want to use SI units. Thank you in advance for your help, Gaspard.
