I have difficulty at the time of the material in the SW to Customize static simulation as follows:
I make the material attached to the unit defaults Customize SI-N / m ^ 2 (Pa),
At the moment I would change it to the simulation units to Metric (MKS)
Every time I can always go back to the default units units, namely SI-N / m ^ 2 (Pa),
How do I change the default unit?
