Dear Autodesk Simulation CFD experts,
I am wondering if the following is a sound approach:
I am solving a conjugate heat transfer case that include several internal fans. So, I want to run the flow only with forced convection truned on (steady state), then, solver the thermal only with transient. So, during the flow only stage, can I turn on adaptive meshing to make sure that the flow field is fully converged?
Solved! Go to Solution.
You would not use teh Autoforced Convection option.
You would run with Flow only checked, thermal would not be on, then solve with adaptation on to get your mesh cycles solves based on the flow solution (be sure that you specify a large enough iteration count to get to a well estabilished flow solution (2-300 iterations minimum)
Once you've solved the flow solution + adapted cycles, you can turn off Flow and turn on Thermal and switch to transient to do the Transient Thermal solution
I just tried, but, the Simulation CFD won't let me because I have a baffle in the model. Is there a way to work around this?
CFD 2013 does not allow for any special materials with Mesh Adaptation
CFD 2014 does
You can update to the latest version or change what you are modeling.
I am using Simulation CFD 2014. In my model, I have a baffle. 2014 won't enable adaptive meshing because I have "surface parts". Is this correct? Or am I missing something?
While 2014 did expand Mesh Adaptations ability to support more special devices (resistances/fans/blowers/etc) it does not support surfaces parts. You would have to reconsider that for adaptation to move forward.
