Re: [Yade-users] [Question #695542]: Unstable advection simulaton for gas flow
Question #695542 on Yade changed: https://answers.launchpad.net/yade/+question/695542 Description changed to: I am trying to simulate advection with a hot gas flowing though a cold packing. I used this example [1] and only modified the fluid properties to represent vapor. I used fluid density of 0.013 kg/m3 and heat capacity of 1996 J/kgK and viscosity of 0.00013 pa.s. The problem is the model becomes unstable. I reduced the timestep by two orders of magnitude and still no luck. So, I was wondering if there is any other parameters I should modify to make the model stable. One more question: How can I specify different thermal properties (like conductivity) to different spheres in the model?
