Hi everyone,
I am working on a Data Center simulation (Conjugate Heat Transfer - CHT) using SimScale, and I am facing a recurring error related to material assignment and solid bodies. I would appreciate some guidance on my workflow.
My Workflow & The Problem:
I imported a volume from Revit that represents my airflow domain (the room). Note: This volume is hollow inside.
Because I needed to define specific areas as “cabinet doors” (inlets/outlets), I performed an ‘Extrusion’ to create these volumes and then a ‘Subtract’ operation to integrate them into the main volume.
The Issue: Since I performed the ‘Subtract’ operation, the software now views these doors and the main volume as a single, complex solid body. It forces me to assign a physical material to all these parts, but these are meant to be airflow interfaces, not solid parts. If I don’t assign a material, the software blocks me from proceeding.
Questions Regarding Power Sources:
4. For the server heat loads (Power Sources), I am unsure how to represent them correctly. Should I draw a small “box” inside the flow volume to represent each server? If so, how should this box be defined within the flow region without creating the same solid body conflict I am currently experiencing?
What I have tried:
I have been advised to use ‘Delete Body’ in the CAD Edit mode, keeping only the flow region.
If I delete the solid bodies of the cabinets and doors, will the boundaries (the imprints) remain as selectable faces on the main flow volume?
What is the best practice to create “inlet/outlet” interfaces on a flow volume without adding solid bodies that trigger material assignment errors?
For my perforated plates (Porous Media), should I keep them as separate solids and leave them as ‘Unassigned’ in the material list?
I have attached a sketch of my geometry (“1000406318.jpg”) and a screenshot of the material error (“1000406317.jpg”). Any advice on the correct CAD-to-Simulation workflow would be highly appreciated.
