Hello Everyone,
I am trying to do thermo structural analysis in optistruct. later I have to continue optimisation on structural analysis. Basically thermal expansions are only load for my optimization problem.
I faced following difficulties and trying to resolve them,
1. thermo structural analysis in optistruct- ---- I have referred all tutorial and discussion available a I did find any direct method to read temperature from my thermal analysis and apply it as load in structural analysis. I have pipe carrying hot fluid and I have convection heat loss so direct TEMP use in static is not possible for me and off course I have referred Coupled Linear Heat Transfer/Structure Analysis , however problem is I need to use structural subcase id as reference to my optimization so I cant use CASE_UNSUPPORTED_CARDS control card.
2. How to request temperature output in static analysis---- some how if I am able to run structural run with TEMP in static analysis, I will have to compare my temperature contour. So how can I request thermal output in static analysis results. (already have tried loadstep--> edit-->OUTPUT-->THERMAL. didnt work)
3. How can I use DRESP2 in optimization, already have found one discussion on same but corresponding tut link is expired. Basically I want to use relative displacement in my optimization as constraint.
Thank you
