I’m trying to create a simple CHT model of a heater heating fluid in a pipe. I was able to import the STEP file with 3 solids (heater, pipe and fluid). However, on meshing I cant get the cell zones to generate so when it comes to generate the interfaces I cant do it. I followed the meshing tutorial https://www.simscale.com/docs/content/preprocessing/meshing/hex-dominant_cht_electronics-cooling.html exactly. I’ve also tried uploading the geometry in different formats bu with no success. I’m not getting any errors with the mesh. I’m just not getting the cell zones generated so that I can define the interfaces as in https://www.simscale.com/docs/content/tutorials/tutorial_cht_electronic_cooling.html.
