I'm having problems adding lids to this part. I want to add lids on each opening (6 in total, 2 per channel through part), all of which will have boundary conditions (mass flow in to planar face entry, environmental pressure at larger exit holes). The problem is that I cannot add lids to the larger openings as they are not on a planar face.
Here is what I have tried:
- For the larger ends I used "create entity" for a 3D sketch then extruded that 0.05 mm to create curved lids.
- For the openings on the planar face I added lids using the add lids feature - seemed to do it but does not allow me to then apply a temperature condition to the face.
Any help appreciated as I'm new on here!
What does it say when you try to add boundary conditions to those lids? My guess is "not lying on the boundary between solid and fluid" which means that your other lids do not completely close off and create a trapped hollow volume for the fluid.
With your shape I'd likely be inclined to make the lids by using the profile shown in your bottom picture and extruding a thin region all the way across (either inside or outside).
