'CHT test' simulation project by lcltech


I created a new simulation project called 'CHT test':

CHT test

More of my public projects can be found here.


Hi @lcltech, we created a step-by-step tutorial for CHT. You can find it here: Step-by-Step Tutorial for Conjugate Heat Transfer (CHT) Webinar


Hello @lcltech,

I think you are trying to perform a conjugate heat transfer (CHT) simulation. There are certain geometry and mesh prerequisites to setup a CHT simualtion. The geometry should contain the solid and fluid regions as independent volumes which are non-overlapping, but the surfaces touching each other. This would enable to create interfaces between the different regions. Please have a look at the following project for a model geometry for CHT. A trial mesh is also done on the geometry.


For a CHT simulation the Hex-dominant parametric mesh needs to be selected maintaining TRUE option for “Create multiregion mesh”. This enables us to setup a CHT simulation. The following tutorials might help you to create the mesh and setup the simulation successfully.

Please try to create different volumes (solid and fluid) for geometry and follow the tutorial procedures to your problem. Please do not hesitate to contact us for further queries - we would be happy to help :slight_smile:
