We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Try switching to Level Set Method.  It might be more robust for your convection load.  Refer to the Mechanical USers Guide=>Optimization Analysis Workflow=>Apply Design Objectives and Constraints...Thermal Compliance...

For the Topology Optimization - Level Set Based and Shape Optimization methods, the Thermal Compliance option uses a unique formula regardless of the context. That is, it executes in the presence of Heat Flux, Heat Flow, prescribed Displacement, Convection conditions, and/or Internal Heat Generation.
