Hello, researcher. I have two very confusing questions, as follows:
I am currently confused about the concept of two-dimensional simulation, as shown in the following figure. Regardless of the size of the rectangular model, as long as the number of grids in the Z-axis direction is 1, it can be considered a two-dimensional simulation. Is this understanding correct?
Do we need to establish wall boundaries when conducting two-dimensional simulations? I checked the user manual and said: as long as the number of grids in the Z-axis direction is 1, there is no need to establish wall boundaries. If that’s the case, what should I do when I need to set the boundary temperature for 2D simulation?
I believe you are correct about question #1 - a simulation with a single cell in the Z-direction is considered 2-dimensional, regardless of the size in the Z axis.
Regarding question #2 - although it is not necessary to set up the Z-boundary walls, I believe that it is still permissible to do so, for example if you need to specify wall temperature, etc.
Sorry Jeff it was me who wasn’t clear. I was asking, I found that when in pseudo-2D, if the front and back wall surfaces are not defined, conductive heat transfer between the front and back wall surfaces and the particles still occurs for particles near the front and back wall surfaces.
