I am trying to simulate the Vacuum Assisted Resin Transfer Moulding (VARTM) process in Fluent. It is basically having a fluid injected into a vacuum containing a fibre preform and seeing how the fluid flows inside it. One of my profs suggested to just have one phase, ie the fluid, and have the porous medium on the section I want it. I tried this, it didn't work at all how I thought it would. I went back to trying to simulate the fluid flowing into the vacuum but I get a floating point error. The model is just a square block of small thickness with a cylinder in the middle to simulate the tube inlet. I simply put the inlet as the bottom part of that cylinder (ie a circle) at 1 atmosphere pressure and the outlet as the sides of the thickness of the 3D square block at 0 pressure. Someone please help me this is quite urgent and I am COMPLETELY lost on what to do. I can upload my files on Google Drive for people to check them out but this will take hours so will have to do this tomorrow if needed. All I need is one phase flowing into another and observing how it flows inside it, that's it. Am I asking for too much? I followed this video (https://www.youtube.com/watch?v=oH5tIdmXusM&t=304s) to the letter and I get this floating point error somehow. My mesh is good I followed guidelines online it's for 100% not the problem. Please help me this is very important.
