Topology optimization thermal compliance optimization

Altair Forum User

Hi,

I am trying to do a topology optimization, refer to the following example. I have a design space(yellow) and a no design space(grey). In this last, there are a thermal flux(QBDY1) and a temperature(SPC) distribution. I want to make a topology optimization using the thermal compliance of the region of design space, because i want exclude the elements outside a fixed temperature range.

I also attached my FEM file, for your reference.

What is the problem you are facing while running the model?

Hi Rahul,

i can not setting this type of optimization with thermal compliance, can you control the errors in my model?

I seen tutorial OS-E: 0880 and the forum about this problem.

Please check attached deck..From loadstep I unchecked Subcase section : STATSUN STRUCT. Activated upper bound instead of lower bound.

Thanks Rahul,

the model works now, but i can not regulate the range of temperature of the final structure. Moreover, how can I obtain the tree like structure optimal shown? Is it possible?

I have shared sample file for tcomp for 2d/3d in another post. Did you try applying any manufacturing constraint.
