Ansys Autodyn SPH Problem
Hi guys. I am having an issue with Autodyn. I'm trying to simulate a raindrop of diameter 3mm impacting a plate with the dimensions 6x6x0.4mm at a velocity of 100m/s. I have setup the model and applied Lagrangian settings to the plate and modelled the raindrop as a sphere with 14328 SPH nodes. I have carried out previous simulations modelling raindrop impact against structural steel to check the model. I am now trying to simulate the raindrop impacting a gelcoat material and impacting an epoxy resin material. In both instances when the simulation runs the sphere appears to pass through the plate. There is no pressure being recorded as I would expect. I am curious if anyone has experience of this or any advice anybody can give me would be greatly appreciated.
