Hello,I am new iq eusto forum. I am a student of aerospace ing; I am working on my thesis concerning the design of a thermal shield.as input data I have the trend in the time of the thermal flow in the stagnation point.
I have to carry out this analysis with ansys...my problem is that if I design a rectangle with height my thickness and I apply the thermal flow on one side and the temperature always on the same side the steady-state analysis does not converge and I do not know why (in theory solves fourier that is of the second order, I check two conditions, one on the flow and one on the temperature and should go well... )
However, non-stationary analysis converges. ...suggestions to the rigurdo? ?
Then, wanting to simulate a load not constant spatially I divided my rectangle into three rectangles..on the central one I would like to apply a constant load and on the other two linear ones (practically a trapezoidal load). ..how do I apply the load to growing trend? ?
I hope someone can give me some answers because I don't know what to think about and time strings:frown::frown::frown:... thank you
