    Transient Heat Transfer [Acusolve]

    Thank you for instructions, I will try this
  2. Hi everyone. I have a question regarding the initial temperature boundary condition in acusolve transient heat transfer. Initial temperatures of body and fluid are known. I used Nodal initial condition to provide initial temperature. How to assign initial tempreatures of the volume and surfaces? Thanks in advance for help.

    Thermal analysis in Optistruct - Gap elements

    Thanks for Your answer, I had a break and now I came back to this issue. I'm afraid I didn't explained it well. The thing is that between shell and solid part I need a medium so I'm using gap elements. When I run analysis as a result I see solid part have temperature like hot side e.g. 500 C and shell elements (part 1) have an ambient temperature e.g.25 C It looks like gap elements do not transfer conduction between them. When I don't consider convection gap elements transfer heat and both parts (1 and 2 ) have hot side temperature. Hope now situation is clear. Do anyone have an idea how to solve it?
  5. Hi, I have a problem with heat transfer in Optistruct - I have solid elements connected with shell elements using Gap elements, heat source is temperature on solid elements and there is two cases: 1. gap elements work properly when there is only conduction heat transfer between those two components 2. gap elements do not work properly when I add convection between ambient and shell elements. Do anyone have an idea what is wrong and could help me solve this issue?
