Small Time Step Size at Caitlin Samuel blog

Small Time Step Size. The reciprocal of the time step size is one divided by the time step size. \$\begingroup\$ time step too small is usually the consequence of a shock or discontinuity on your models. Usually i set max iteration per. Even the most complex problem with a poor mesh converges because essentially nothing happens. The bigger the steps the smaller the value. In most default transient solvers comsol has the flexibility to increase or. Hi, a rule of thumb is to set time step< deltax/u. If you are using the les turbulence model with a small time step size, the piso scheme may be too computationally expensive. The wave propagation velocity for membrane deformations determines the critical time step. Smaller time step sizes require more computational time and resources, as each time step must be simulated in detail. Therefore, engineers and researchers must strike a balance between. It indicates that the solver could not achieve the desired. Where deltax is the smallest cell size and u is the velocity.
