Transient Analysis of electrical geezer
 

Hey,

For my project at the university i have to analyse an electrical heated geezer for warmwater in households. This is my first CFD-Analysis and therefore i´m not very experienced in this subject. Now to my Problem: Because i wasn´t able to model the buoyancy of the water during the heating process i switched from fluent to cfx.
In the first step i was modelling the heating process of the water inside the geezer (transient 15 timesteps over 2.5h). Afterwards i wanted to simulate an usage event (transient 10 timesteps over 810s). For the initial conditions i chose the result file of the heating simulation. When i now start the solver everything works perfect. The right values are initialized and the first timestep (2.5h + 81s) seems to be calculated right. But after the first timestep the program finishs.
I tried different option settings in the cfx-pre window but the result was the same. Could anybody imagine where the mistake was made?
Kind Regards

I found the mistake, reading through my own queastion:D. I had to set the total time of the analysis to 9810s. Because it starts from 9000s and not at 0s.

Hope not to have disturbed anybody:rolleyes:
Kind Regards Luis
