Dear SolidWorks Forum, I am currently working with flow simulation and dealing with a fluid that is supercritical in nature. I have all the gas/supercritical fluid properties to conduct flow simulation; but, the engineering database won't allow me to input temperature dependent density. It allows me to input dynamic viscosity, thermal conductivity and specific heat; but, not density in the user defined fluid option. Because the fluid is supercritical, the standard equations that flow simulation uses to calculate density are incorrect. There is a significant error. Therefore, I would like to have an option to input correct densities. It doesn't allow me to do that. I request an added functionality to the User Defined options to incorporate densities. Have any of you encountered this issue? Thank you.
