I am trying a heat conduction problem with moving source. To simplify the problem, I used adimensionalized variables, but this resulted in a very little non-dimensional time domain: less than 10^(-4). I found some problems, because it seems that the simulation does not work properly. Do you have some ideas to solve the problem without changing the adimensionalization time scale? Thank you for your help, Alberto Borboni |

If u choose to use thermal diffusivity and characteristic length, it will shrink ur time scale as u said. There are many other ways to normalize the time, use characterisctic length and linear speed for instance: dimensionless time tau = V/L * time. Choose cahracteristic length (L) properly then ur dimensionless time may be shrunk or stretched accordingly. Hope this helps... /Mongi |
