Problems with Simulation
 

Hey Guys,

im really new to CFD-Simulation. Though i dont have acces to the Ansys Customer Portal i just started trying some things...
Right now I´m doing a 2d-Simulation of a compression in a chamber.

Attachment 30183

I use Ansys Workbench 14.5 and designed the half of the geometry(axissymetric) and the mesh with Ansys.I seperated the geomatry in 5 surfaces and connected them with interfaces. I used quadrilateral meshing with a higher density near the interfaces. Mesh Check was positive.

In the setup I used Dynamic Meshing,In-Cylinder-Motion and Layering as Mesh-Method.

When I start the the calculation i get following message:

Error: replace_c_in_f_layering: cell of wrong type or NULL cell detected at layering zone.




Now I have a few questions:

How can i fix this proplem?

When i check my Zone Motioten...is it normal that I can only see the top surface that is not deformed?

How can i get acces to the data of the Ansys Customer Portal to do some Tutorials?

If I use the Mesh-Motion function i get the message: Note: zone-surface: cannot create surface from sliding interface zone. Creating empty surface.
Is this a big problem?


If you have some tips for me I would like to hear them.
Thanks Guys

Tried to use different Meshes, but im getting the same message as before...
any ideas what could be the problem?

My simulation seems to work now, but during the calculation i get another error...

Error writing "| gzip -2cfv > C:\Users\xxxx\xxxx\xxx\xxx\dp0\FFF\Fluent\FFF.1-1-01200.cas.gz".

Anyone knows what this is?
