  1. Hi Girish, yes, I am using 2019.2.0 version.
  2. Hello, I am writing to ask how correctly set FRA analysis? I've made an example with simple plate: 1.Modal analysis: 2. FRA analysis: - frequency function like that (just for example) - base excitation - acceleration 3. Result: Result isn't the same as in modal analysis as I supposed to. I expected peak values in 26Hz, 116Hz, 169Hz where resonace will occur. Somewhere I made a mistake, can anyone help me?
  3. Thank you for instructions, I will try this
  4. 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.
  5. Hi, do you have any information about a problem?
  6. 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?
  7. 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?
