Dear All
I am simulating a 3D sphere travelling in a pipe filled with water under transient conditions. The geometry has around 1m elements, and I am using 0.001s time step size with k-w sst solver. The issue is about running the model for longer time with no problems, and as I was trying to make quick by reducing the Max Iterartions/Time Step or increasing the time step size, I get that error. Basically there are three dynamic mesh zones with a cell height of 0.005m, so is there a proper way to estimate the best value of it? Please give me a hand in this problem I am having. Regards, |
