overlapping contact regions
overlapping contact regions
(OP)
Hi,
i'm making a CFD (Fluent simulation) of a battery with a lot of compontents. Around the battery there's an enclosure. This air enclousure is around but also inside the battery (air channels).
There are a lot of contacts beetween the components and after the meshing operations i have overlapping regions. How can i fix it?
I need automatic contact regions for save time because the geometry is complex.
Please help me!
I attached some pictures:
Thanks in advance!!
ps: i decreased the contact tolerance to a low value

RE: overlapping contact regions
so i have to split a single surface in many surfaces to build one contact to contact surface?
The surfaces created in spaceclaim have to be treated through the named selections?
Thanks!
RE: overlapping contact regions
Like previous poster mentioned, you should look into
simplifying the geometry more.
RE: overlapping contact regions
What do you suggest? Use named selection to by-pass this problem?
thanks again....
RE: overlapping contact regions
attached I post an example of the contact problem that i found makinf "repair overlapping contact" (after the program automatic repairing the contact is suppressed).
In the attached image I have insulated only 1 failed contact.
Consider that i have yet made the following corrective actions:
- Contact tolerance increase (1e-5 mm)
- Geometry facet tolerance increase
- Coupling beetween 1 target face and 1 contact bodies
Due that i have a lot of failed contact maybe i'm missing some important setting.
Please help me!!

PS:
do you now a free post processor for this need?

You can use user defined results to sum the values if you have several boundary conditions.
If Workbench cannot create directly the result you need, you can script it via APDL.
Please state what you want to output in detail, possibly with some pictures, so we can determine
if scripting is needed.
