To simulate the air outside the house flowing in, I tried to use the external flow volume function. When I tried running it without inputting anything, I got the error message: “The flow region could not be created. Please search for potential problems around the following entities… and consider cleanup operations in your CAD tool.”
To try and solve this problem, I then tried to form a union between all the walls and doors in the house to only meet another error message: “Union operation failed as the result does not constitute a usable manifold body. Trying narrowing down your selection set, or contact our support team for assistance.”
Hello, after tinkering around for awhile, I have reached the simulation step.
However, I got the error message: “A setup with 37 regions is being used in a single-region analysis type. Please make sure that all regions except for one have an Advanced Concept assigned to them”
The first advice is to make a boolean union in the CAD software, which I have already done, and the second is to select ‘Add geometry operation’ and merge all solids into one.
I tried to choose a random window as a seed face, and the outer walls as the boundary faces, but that did not quite work out. May I know what I should do in this case?
But I had some confusion initially, which I thought I should mention for others’ reference.
Initially, I chose the window as the seed face, and the inner and outer walls as the boundary face, which gave me this error message.
