Hello,
What are the units of pressure given in Hyperworks CFD? Assume they are Pa or kPa?
Thanks
Currently HyperWorks CFD (like AcuSolve - the solver itself) there is no concept of units. Everything needs to be created, specified in a consistent set of units. If you're working in MKS - distances/lengths in meters, temperatures in Kelvin, time in seconds, density in kg/m^3, etc - the pressure unit is Pa.
Hi all,
If i work in mm Kelvin second system in my CAD system, and from that i imported my geometry in to the CFD, my unit system will be the same? So the pressure will be kPa?

Best first to use the Measure tool to determine the dimensional units represented after import. If the values measured do indeed represent mm, then you need to make sure all material properties, boundary conditions, etc are consistent with lengths in mm.Personally, I would specify to import the geometry in m (or scale if still mm), then use values consistent with the MKS system.
