I am modeling pleated air filters and the flow simulation never recognizes the pleats. Even when I set a local mesh only on the media, it never has a closer mesh. If it cannot recognize the pleats, I cannot use the industry gathered data to test with.
Does anyone know how to make the flow simulation recognize the pleating?
The media is in a frame that is approx. 2x2 ft and the media .33 mm thick.
Thanks for any advice.
Sounds like your initial mesh is too coarse. If it is too coarse and there is too great of a difference between the control and global, it won't refine. Take a look at the technical reference for more info.
But please post some pictures of what you are working with. Especially how you are determining it isn't capturing the pleats. Your version and service pack may be important considering 2012 and. 2013 made serious leaps in using less cells to capture geometry.
Also, while you are in the technical reference, check on limitations with porous medium. I don't know if a complicated shape like I am imagining you have is supported. Since you are replacing the filter with porous medium, I might suggest replacing it with a simple cylinder or cube as a first pass.
