Heat Transfer Steady State Analysis

I am using Heat Transfer Equation mainly Heat Flux Q = A*Alpha (T_gas - T_body), where I have both the cases Conduction and Convection. I am using Optistruct but I have seen that in Radioss it explained very nicely. I don't know the concept of Heat flux and the equation which I am using that also the same in Optistruct?

How it works because T_body and Q(Heat flux) are unknown here. Please give me some of example and Explainations.

Thank you,

Regards,

Hi Jay,

Please see the example model attached which is a heat source moved on one plate. Heat exchanged between a heat source and a plate through contact, also between a plate and the atmosphere (water) through convective flux. The pdf and model files are attached for your reference.

Meanwhile we have several tutorials available for OptiStruct.

Please refer:

Thank you for your Reply....

I would like to know that in hypermesh Optistruct, after getting result, do I find in Input file Information about Area of each section, and graph for Heat Transfer Coefficient like Legend form.

Because I Need heat flux which I will get after multiplying Area to my heat flux at particular Point or node, Q = A* q(dot) = A * Alpha* (deltaT).....

Thanks,

Regards,
