Hello everyone,
I am currently using Hyperworks for my analyses and have encountered an issue related to the unit system. Initially, I specified the material properties in the unit system t-mm-s-N-MPa, following the standard specifications for steel. However, I later decided to switch to the SI unit system: kg m s N Pa. To do this, I set the SI system via DTI units at Cards and also in Model Verification-Check Units.
The problem is that when I specified the material properties in the SI unit system, I obtained completely different results compared to the default unit system. I have read in the online help that Hyperworks is unitless and it's the user's responsibility to adhere consistently to a unit system, but this general information didn't answer my specific questions.
Hence, I have the following questions:
- When defining the properties of a material, do I always have to specify them in the default unit system t-mm-s-N-MPa, even if I have changed the unit system under DTI-Cards?
- Is the output also in the units specified in the default system, or is there a way to display the unit system in which the results are output? Alternatively, is there any option in Hyperview to display the units if I specify them beforehand? In other words, is there a way to check the units once they are generated?
I appreciate any insights or suggestions to help resolve this issue. Thank you in advance for your assistance.
