I am attempting to model the inside of a thermos for a project. Right now I am using ANSYS 18.2 APDL, and am running a 2D axisymmetric simulation.
The model consists of two walls and a top cap that are rotated axisymmetrically. The element I am currently using is PLANE55. I am incorporating conduction, convection, and radiation. There are a few problems I am having.
- Not sure how to model the hot water inside. Currently using PLANE55 elements with the thermal properties of water.
- My radiation isn't working properly. Do I need to use a LINK31 element to make it work? I need to radiate between the walls and to the outside.
- Different areas aren't conducting to each other. Is there a way to set up contacts like there is in Workbench?
I have included the .db for this if it helps. I appreciate any help!
