Simulation CFD 2014 - Simulation hang up while saving / can not stop

[marcel.mueller]

Hey!
I have a Problem with Autodesk Simulation CFD 2014.

1. Goal:                                            I want to simulate a Transient Heat Transfer in a Semiconductor Device.
2. Model:                                          from Inventor 2014 -> Picture 1
3. Materials:                                    copper / silicon / aluminium -> Picture 1
4. Boundary Conditions:              4.1 Total Heat Generation in Chip / Picewise Linear / Plot -> Picture 2
                                                         4.2 Constant Temperature on buttom Plane = 23°C -> Picture 3
5. Initial Conditions:                     All Parts have a Initial Temperature of 23°C
6. Mesh Sizing:                             Automic Mesh
7. Solve:                                         7.1 Physics: only Heat Transfer
                                                        7.2 Control: -> Picture 4
8. Solving without saving:          The Simulation runs, but without saving Points T(t). -> Picture 5
9. PROBLEM:                               solving with saving:
                                                        when you want to save Intervals (-> picture 6), Simulation CFD hangs up (-> picture 7),
                                                        means:
                                                       you can watch the Convergence Plot to the Point of first try of saving (2 secounds /     
                                                      Picture 7).
                                                      You can not stop the solving progress. Also a restart of the                 
                                                      Programm does not solve the "Stoproblem". You have to restart the Computer,             
                                                      after that you can stop the solving, but without saving of any solutions.

1 - Model and Material

2 - Boundary Conditions - Total Heat Generation

3 - Boundary Conditions - Temperature

4 - Solving without saving

5 - Solution without saving 1

6 - solving with saving 1

7 - solving with saving, hang up
