Hello,

I´m trying to simulate a Temperature dependant Water Volume.

I built my model with moving meshes. The mass of my water is constant and moving mesh direction is just in z-direction. When i start my simulation I get an Error "Singular Matrix". Can anybody help me with my model?

Thanks!

Alessandro

I´d like to specify my problem.

I have a water domain. At one boundary there I defined a temperature - so in my time dependant study the temperature of my domain is rising up. The mass of my water is constant - so because of the temperature variability of the density the volume has to grow! I want to simulate that problem with a moving mesh. I know that I have to do it with integration but I don´t know how! Maybe anybody can help me - I attached a simple model.

Thanks!
