Hi, im new using the CFD Simulation, and i opened the tutorials, but the videos dont work in my browser, i just have request. Im doing a study of heat transfer, the ambient is a -173°C Nitrogen gas, i export the geometry, but i dont understand where of how put the test tube initial temperature (23 °C), or the heat convection transfer coeficient. I suppose the dimensions are imported too with the geometry. Thanks in advance.
